Server Freezes While Doing Checkpoint ?!
Jul 24, 2007
We're running the Microsoft product SMS 2003 SP1 for software deployment, patching, hardware inventory, etc. The back-end is SQL 2000 Enterprise SP4 which is installed on the same box as the SMS 2003 SP1 product, and the DB is 145GB's.
We started noticing that the server would freeze every minute or so for 30 seconds. We started logging stats via perfmon and saw that the average disk queue length for the physical drive of F: would skyrocket between 400 - 500 for 30 seconds at the same time the freezing occurred. I have determined that this is occurring during the checkpoint. The recovery interval option is set to the default of 0 on SQL, when I changed the setting to every 5 minutes, the average disk queue length for the physical drive of F: would skyrocket between 400 - 500 every 5 minutes and would subside after 2 minutes. I understand the need for the checkpoint / recovery interval option, but don't believe this high average disk queue length should be occurring.
Does anyone know why this is happening and how to fix this ? The freezing of the box while checkpointing is killing me.
Thanks

Hi, I'm using SQL2005 v9.00.3042.00 (SP2) on Windows 2003. I have a situation, when I turn on and begin to trace a database using the "SQL server Profiler", that particular VB application that uses the databases freezes (hourglass) when user click on anywhere that require a data query (download list, etc.) until I either pause or stop the trace, what gives? Thanks in advance.

Set up - windows server 2003 - SQL server 2000 + tools installed
Not sure why its happening but recently when running some scripts onto one of the databases held on the server windows crashes.
I say crashes - it is non responsive but the mouse cursor can be moved.
these scripts are not being run from the server but from one of many machines on our companies network.
Any suggestions would be great

We have SQL 2000 running on Server 2003. The server has 4 GB RAM, RAID 1 and has the /3GB switch in Boot.ini. We have 6 databases, the largest is about 14 GB. Until recently I could use Enterprise Manager to perform database backups to a folder on the same server but now the operation fails. After selecting the location for the backup and clicking OK, the hard drive light comes on but goes out after 15 - 30 seconds. The progress bar does not move. I've waited and waited but nothing further happens and the server doesn't respond. The only solution is to push the power button and let the server re-boot. Very occasionally the backup will run for a minute or two and the progress bar might get to about one third of the way across, (in which case the destination file will show up with more than 0 bytes), but it never completes. I can find nothing in the event log relating to this problem. As far as I am aware, nothing has changed since the last successful backup. Backups to tape using Retrospect appear to work fine but I haven't done a test restore. Does anyone have any ideas as to what I can try to get the backups working again?

Hi,
The SQL Server Database hangs overnight and also consumes high disk space on one of our servers. This has been recurring for quite a few weeks and occurs daily.
Can somebody assist me in trouble-shooting the same

I have a Database that is set to Simple Recovery mode.
It is not clearing the log and the transaction log is growing.
I thought that it would clear the log upon checkpoint?
How can I force the Transaction Log to clear since NO-TRUNCATE is no longer available?

Ok,
My SQL Server production DB freezes for 20 minute periods about 3 times a day, during
this time no-one can do anything. I checked the perf. monitor counters (all
the ones there at default), the scary part is that they ALL fall to 0 during
the freeze, then rise to normal. Yes, that's zero %!
I checked the ID's connecting, there are no common ones that connect just
before a freeze, and there are no hardware issues. It's only a 400Mb DB,
with a trans log of 120Mb. Between 200-400 users are connected during
business hours, both from the LAN and off. Some users are running some
fairly heavy reports, but there's no correlation between these and the
freezes. The biggest table only has 1.5 million rows, and the average query
time is 232 milliseconds.
This whole mess has been going on since the 15th of Jan, we searched high
and low for any alterations made, but the client swears blind that no
changes were made. Any ideas anyone?
Thanks in advance all,
Jaishel.

Hi,
the SQL DB freezes and no one can access the DB for 5 or 10 minutes. Even select queries don t execute, nothing is displayed.
Until we kill the process id that s blocking in the sql activity monitor, only then the DB is released and people can work again.
What does it mean that no query executes until we kill the processes ID? what could it be?
Also, recently we created indexes and ran tuning adviser, is it possible that the creation of indexes cause the freeze of a DB? is that possible?
Thanks a lot for your help

Hi all !
Hi have a package with 3 steps :
1 - import data from flat file into a temp table
2 - copy selected data from the temp table to permanent tables
3 - truncate temp table
The task #2 is a SQL statement
INSERT INTO MODELS (MODEL_ID)
SELECT DISTINCT MATNR
FROM STANDARD
WHERE MATNR NOT IN (SELECT MODEL_ID FROM MODELS)
where STANDARD is the temp table and MODELS a permanent one. My problem is this simple task freezes all the time. It stalls on 'Starting' and stays in this state forever when I execute the package.
Any idea why ?

I am installtion MSDE on a Windows XP Pro. The install gets through to 5 seconds and freezes. THis sits for about an hour and nothing happens. The Microsoft SQL Server folder is created, but the services are not created. We tried to reinstall many times and removed the registry key before each reinstall (after uninstalling and rebooting). Any ideas about what could be wrong?

Hi
We are repeatedly having the trouble of our publisher database becoming unresponsive during network problems.
We have publisher in carribean, distribution agent in canada and subscribers all over. The problem comes when publisher cant deliver to distributor due to network outages.
We are planning on moving the distributor to the carribean ultimately but that will take a while, and our application repeatedly needs to be restarted due to these freezes.
Does anyone know of this problem & possible ways to fix it in the short term (short of changing our replication topology).
is this a bug in replication?
ps.database is merge & transactional pubs. (some tables merge/some trans)
help much apprec,

I am trying to move data from a transactional database to a data warehouse using a slowly changing dimension. The transactional data comes from a view in SQL server that takes <60 seconds to run and returns about 60k rows. The warehouse table is currently 80k rows long (and growing), and contains 7 historical (type 2) dimensions. When I execute the package in BIDS the DataFlow Task begins to execute, and shows that between 20k and 30k rows have been pulled from the data source into the SCD Transform in the first hour before it simply stops doing anything. This is not to say execution stops; it continues. There is no error thrown. No warning given. System resources are 98% free. The database is not being hit at all. And yet, I have let the package sit 'still' as it were for over 8 hours, and nothing ever happens.
Here is a copy of one log:

Notice the time difference between the last OnPipelineRowsSent event and the first OnError event (when I clicked the stop button): 5 hours! In all that time, SSIS did not log a single event, or use more than 2% of my processor or exceed 1GB page file or hit the database even once! I am assuming this means it is simply not doing anything. It is not failing, nor is it executing, it is just sitting there.
Has anyone experienced a similar problem? Does anyone know how I might troubleshoot this? Thanks in advance for any help, and let me know if I need to clarify. Also, I am new to SSIS, so if I am missing something obvious, go easy on me! Thanks.

Hi Everybody,
I am having a very weird problem, and I was wondering if you have any idea about what I could do to fix this.
In a nutshell:
* I have this application that uses ADODB and ODBC to connect to an SQL database.
* We have two installations: one running SQL 2000 sp 3, and the other SQL 2005 sp 1.
* The one that runs on SQL 2000, my app performs 8,500 transactions a day with no problem.
* The one that runs on SQL 2005, my app performs 200 transactions a day, and goes down at least once a day.
Trying to figure this out, I noticed that, from time to time, when working with SQL 2005, the application kind of freezes when it tries to read or write to the database, and after a while (say 20 seconds or more), it continues as if nothing had happened. Trying to debug this issue, I noticed that this wait time period is ended if I close one of the other open connections that I have (say, I close the query analyzer)
As people may say, ADODB and ODBC should no longer be used... however, I have noticed this same kind of behavior with other tools, like the query analyzer from the SQL 2000 client tools when connecting to the SQL 2005 server.
I suspected a Licensing issue... however, I haven't been able to replicate this problem by opening several query analyzer instances.
Any help is greatly appreciated!!!!!
Best Regards,
Manuel

To the Moderator:
I am not sure if this thread needs to go into this forum or there is one for C# stored procedures/CLR Database Objects.
To All:
Is this a known issue that when debugging CLR stored procedures the VS 2005 freezes even before reaching into the stored procedure? I can restart my computer and debugging works for a while and then it starts to take forever when I step into (F10) during debugging. I am running only one instance of sql server, and even that of my local machine as I have never been able to debug on a remote server.
This random and unstable behavior of the debugger is proving very unproductive and costly. Is there a microsoft update/fix/patch to make debugging CLR stored procedures a smooth process?
Thanks.

Hello again!
Once again I got stuck with a weird problem and I´m dependent on you.
I built a Data Flow task in which I did an OLE-DB Source Adapter with a SQL-Query as Source.
The Query goes on a Linked Server which connects to a Informix Table via ODBC. When I enter the Query and klick "OK" or try to go on the "Columns"-Tab, the BIDS freezes completely and the "Delay Notification Message" appears in the System Tray. When I check the Activity Monitor of my SQL Server, there´s a process marked as "Runnable" (green) which contains the Query
"select collationname(0x0904D00034)"
This one is oviously run by Visual Studio and doesen´t execute properly. I waited for an hour or so, but nothing changes. I´m running SQL Server 2005 SP2 (9.00.3042)
Any help would be greatly appreciated!!!
Thanks in advance!

I have a package that hangs in the designer after I change the sql statement in a DataReader Source from a 'select' to a 'call stored procedure'. The stored procedure takes 2 date parameters. I use an expression to build the 'call stored proc' statement and the 2 date strings. The data reader source uses an ADO.Net connection manager. The ADO.Net connection manager uses the provider for MySQL (Connector/.Net 5.1) which I installed from MySQL.com (http://dev.mysql.com/downloads/connector/net/5.1.html). Before creating the stored procedure I had been using an expression to build a 'select' statement with two date variables as follows:
select ...
where ads.last_seen >= "" + (DT_STR,10,1252) Year(@[User:: StartDate] ) + "-" + (DT_STR,10,1252) Month(@[User:: StartDate] ) + "-" + (DT_STR,10,1252) Day(@[User:: StartDate] )
+ "" and ads.first_seen <= "" + (DT_STR,10,1252) Year(@[User::EndDate] ) + "-" + (DT_STR,10,1252) Month(@[User::EndDate] ) + "-" + (DT_STR,10,1252) Day(@[User::EndDate] )+ "" group by sm.service_provider_id,lm.location_id,lm.web_sublocation_id;"
The sql for the data reader source is set via the sql command property of the data flow component.
After testing the sql, I created a stored proc from this sql and then changed the expression (using the sql command property of the the data flow component) to build the 'call stored proc' statement, like this.
"call usp_SEL_Rollup ("" + (DT_STR,10,1252) Year(@[User:: StartDate] ) + "-" + (DT_STR,10,1252) Month(@[User:: StartDate] ) + "-" + (DT_STR,10,1252) Day(@[User:: StartDate] ) + "","" +(DT_STR,10,1252) Year(@[User::EndDate] ) + "-" + (DT_STR,10,1252) Month(@[User::EndDate] ) + "-" + (DT_STR,10,1252) Day(@[User::EndDate] ) +"");"
then when I tried to switch to the data flow tab, the editor froze, with the status bar saying "validating datareader source". The data flow tab says "Loading...". I don't know how to troubleshoot this. Each time I have tried I have had to kill the application. Any ideas/suggestions?
Thanks,
Al

I have a package that uses checkpoint restart. It is resposible for truncatings many sets of tables and then loading them. There are several ExecuteSQL tasks to truncate the tables and several corresponding data flows to accomplish the loads.
If a load fails I want the corresponding truncate task to be part of the restart otherwise duplicate data may be loaded. Normally, SSIS will start at the failed task. I read something about containers that led me to think that if I put the truncate & matching load pair in a sequence container that the container would be the restart point, but either I read it wrong or it's not working that way.
Anybody know how to accomplish what I want to do?

With 2005 SP1. Have built a SSIS package that successfully saves a checkpoint file and sometimes successfully restarts. (I've also built some others that are 100% reliable).
On the unsuccessful restart it appears as though the failed steps and subsequent steps do not execute. the package appears to "complete" though and the checpoint file is removed as though everything is fine.
On a successful restart the failed step reexcutes and everything works fine.
The issue appears that when a failed step finishes at the same time as a successful step finishes there is contention in the process that writes the checkpoint file out and the checkpoint file is corrupt. The failing step runs in parallel with a successful step and the execution times are very similar so task A may complete before or after task B.
Contents of a good checkpoint file follows <DTS:Checkpoint xmlns:DTS="www.microsoft.com/SqlServer/Dts" DTS:PackageID="{3BFFF2F9-74BA-4CE9-8435-81CC198E8144}"><DTS:Variables DTS:ContID="{3BFFF2F9-74BA-4CE9-8435-81CC198E8144}"/><DTS:Container DTS:ContID="{3655F83D-5EA5-4F16-9B8F-520582A1229A}" DTS:Result="0" DTS:PrecedenceMap=""/><DTS:Container DTS:ContID="{DB2D7A57-D405-4B11-AF4A-41B331EE3F15}" DTS:Result="0" DTS:PrecedenceMap=""/><DTS:Container DTS:ContID="{DFC6A95F-CCFA-4FD9-B604-FCBD722B47D8}" DTS:Result="0" DTS:PrecedenceMap="YYY"/></DTS:Checkpoint>

Hi,
I've set up a number of jobs (not a maintenance plan) via a script in SQL 2005. These jobs do the following:
1) Full backup every sunday night
2) Differential backup every weeknight
3) Log backup every hour
The database is obviously in the full recovery model.
The backups all seem to be running, with one issue - the log file is still growing and is not being truncated. I was under the impression that a log backup should result in the log being truncated after each full backup. However, this does not seem to be the case.
Is there anything obvious I've missed that needs to be set up, or is there a way I can check that the full backup is actually setting the appropriate checkpoint and that the log backups are 'seeing' these checkpoints?
Thanks

If i have 3 Tasks in my control flow with checkpoint enabled and the transactionoption of the tasks is required,
Transaction option of the package is supported.
if the second task fails , the package restart from the first task when its running again instead of using the checkpoint and begin from the second task
Can anyone tell me if it€™s a bug in SSIS?

Details: MSDE 1.0 / SP4 - Windows 2000 Pro
I have a database that has Truncate on Checkpoint set for the Log file. The Log file is set to AutoGrow. Is it necessary to to run dbcc shrinkdb (or the like) to get Log file to contract? Is there any harm in not contracting the Log file? I'm looking for best efficiency and least-likely-to-fail path as DB sits 'really remote' and there is little opportunity for observation.
Does anyone have any recommendations on re-indexing? I have one table that bears the most growth. It has a clustered index. What would be a suitable data point to watch? I run a SP to save DBCC SHOWCONTIG info along with the duration of a test query, but haven't seen a clear breakover point.
TIA -RC

Can anyone assist with this problem.
Every now and then my overnight backups (backup Exec) fail due to the truncate log on checkpoint being enabled. This occasionally occurs on Master MSDB databases. I have unchecked the truncate log on checkpoint box numerous times and the backups work fine. Then mysteriously the box is checked again and the backups fail once more. I am stuck as to why this can happen. Is there a generic stored proceedure that checks this box ?
Help with this will be welcomed.

The log on one of my databases keeps filling up, even though I have it set to truncate on checkpoint. the only real difference between this database and the others on my server is that it is built from the dump of another database (on another server) where the tables are marked for replication.
I'm wondering if the fact it is built from a replicating database could be causing this. I've noticed I can't drop any of the table, even though my database isn't set to replicate (or publish).
two questions
1) Any ideas?
2) Is there anyway I can make my server realize I'm not replicating so it will let me drop those tables? (nothing in Enterprise manager indicates that my database is replicating or publishing).
Thanks,
Jim

Hello,
I am DB Developer (not admin), excuse me if this is a silly question.
I don't know much about CHECKPOINT background But I feel, this process is slowing down performance of my sps which runs slower than normal in some cases.
Especially when I see any of my process goes in the suspended mode and its wait type is SLEEP_BPOOL_FLUSH and CHECKPOINTs process is also suspended and its wait type is CHECKPOINT_QUEUE.
More important anything else is... this background process (which I always find its spid is 11) BLOCKS all other user processes when it goes into suspended mode and its wait type is SLEEP_BPOOL_FLUSH
I dont know my analysis is correct (claiming checkpoint as culprit), need experts advice and help
can someone give info on checkpoint and how this effect server performance
