Service Broker Consumes More Memory
Dec 11, 2007Hi,
I have implememted service broker in my application.My sqlservr.exe comsumes more than 2 gb of memory which eventually cause my computer to hang.I unable to track the problem.
Can anyone help me out of this.
Looking at the SQL Server logs i found following error message logged multiple times ;

SQL Server Gradually Consumes All Memory And Brings Down NT
Mar 10, 2000Hello,
After launching MS SQL Server 7.0 SP 1 on a Compaq Proliant 5500 with 1GB memory the sqlservr.exe process gradually consumes all available memory and brings down NT.
This happens when there's appearently no activity on SQL Server.
What's going on?

DtsDebugHost Processes Consumes Huge Amounts Of Memory, Then Fails
Jul 18, 2006I gave up on the ScriptTasks, but desided to use Custom tasks instead. Problem again. My code opens a 400M file and reads it line by line using StreamReader. Each line is approximately the same length. For each line, there is some processing, and then the line is written into another file using StreamWriter. I am watching the DtsDebugHost process with TaskManager open and here is what happens:
Initially its all good. Then when it read through first 150M+ of the input file, the memory usage of the DtsDebugHost shoots up dramatically - about 1Gig (both virtual and physical memory). Then the task fails with OutOfMemoryException. I thought the problem is with my code, but it still happens even if I only read a line from one file and write it to another, without any processing!
When I invoke the same code from Execute Process task, its all good - no problems at all whatsoever.
Any ideas?
Planning For SQL Server 2005: 64-bit, OS, Processor, Memory
Jul 23, 2005I was browsing Microsoft's SQL Server site, looking forsome details about SQL Server 2005. Didn't find whatI was looking for...I'm thinking about moving an existing SQL Server 2000workload to a new box, using SQL Server 2005, andmaybe the 64-bit version.My questions are:1. What is the current target date for release of SQL Server 2005?Will 64-bit ship when 32-bit ships?2. Will 64-bit SQL Server 2005 require a special versionof Windows Server 2003 (e.g. Windows Server 2003 Enterprise x64)?Will it work with both Intel and AMD processors?3. How many CPUs, and how much memory, will be supported bySQL Server 2005, 32-bit and 64-bit, on each OS that can runSQL Server 2005.I'm looking for a chart here, something like the chart onpage 117 of Kalen Delaney's "Inside SQL Server 2000" book.SQL Server 2005 SQL Server 2005Feature Enterprise 32-bit Enterprise 64-bit------------------- ----------------- -----------------CPUs supportedWin Srvr 2003:Win Srvr 2003 Adv:Win Srvr 2003 Ent x64:Physical memorysupportedWin Srvr 2003:Win Srvr 2003 Adv:Win Srvr 2003 Ent x64:Has Microsoft published this info, and I just can find it?

Sep 25, 2006Hi,
We have recently tested upgrading our web service from sql 2000 to 2005 sp1. The upgrade went smoothly enough, however we now have the problem of the sqlserver.exe process taking 90-100 % of the processors time, but using only 100 MB of memory.
We have 6GB available and we are running the enterprise editions of Windows 2003 and SQL 2005.
Machine specs,
DL380 G2, 2 X 2.8 Ghz Zeon, 6GB ram, Raid 5, database partition of 140 GB, Log partition of 35 GB.
Db is 25 GB, Log is 12 GB. Largest table has 32 million rows.

SQL Server Consumes 100% CPU!!!
May 16, 2004The problem is that our production SQL Server ALWAYS consumes the full CPU capacity when in operation. It also does not utilize the full 4G memory alloted to it, but only consistently uses 1.7G. Now, the application using the DB does use a lot of server-side cursors and since the software developer is a 3rd-party vendor, we can only do so much to recommend application optimization. Also, we've discovered that the application modules that were identified as mostly participating in high-CPU utilization does not always consume it highly, although they are the ones mostly involved in it. So, in relation to the limited usage of the 4G-alloted memory, we have theorized that perhaps the SQL processes may be hanging & waiting for each other to complete processing whenever more memory is needed, thus contributing to the server slow down, but this is memory not CPU utilization. We have been wracking our brains for ways to prevent the server slow down due to CPU utilization.
Any feedback will be greatly appreciated.
How To Identify What Consumes Cpu In Sql Server
Jun 1, 2007Hi all
I use 64 bit 2005 server with 8cpu and 8G of memory.
This server is accessed by large number of intensive or not so intensive programs.
I had eliminated all inefficient queries by means of sql profiler. What I see now is 30 procs or so runining in 1 second. They are all pretty simple and as I said use indexes. cpu column for most show 0, reads show 10 - 50 - pretty good.
But... my cpu utilization is 75% in avg. across of all 8 cpu's. I really can't find an answer for it.
If procs run so efficient, where does cpu go? Disk queue length is 0.04 or less - seems very good.
Task manager shows that all of it 75% attributed to sql server.
So which resources besides sql queries use so much cpu? Do I have to look at some other areas and which ones where cpu could be used besides sql queries themselves.
Thank you, Gene.
Database Consumes Available Free Space?
Jul 12, 2012I inherited a SQL server (2005) that sits on a Windows 2003 box (upgrading to 2008 R2 and Win2008, ASAP) and on our SQL Data Drive (260GB - 22GB free) we have 16 databases (that are associated with our primary application). One database in particular is causing me quite a bit of pain - on Tuesdays. This table will consume all available free space (save 700kb) and place it within it's 'reserved' space. It's not being used and I can reclaim it by shrinking. I have done this for 3 consecutive weeks now and I have always thought that shrinking is not really a best practice.
Based on a job I scheduled to spit out various database stats I discovered the following:
Somewhere after 11pm on Monday (and on or before 11:30pm) the reserved space goes from 9GB down to 23 then 37MB on this particular database.
After 1:30am on Tuesday (and on or before 2:00am) the database consumes nearly all available disk space and thus expands its reserved space to 28GB
I believe it has something to do with the Indexes being rebuilt - per the Maintenance Plan the Index Rebuild is supposed to occur every Monday @ 11pm. On 6/18 it ran from 11pm - 11:44pm with no problems. Starting on 6/26 (and subsequently 7/2 and 7/9) they have started at 11 and ended anywhere between 2 - to 3 hours later. And with the following error:
Failed-1073548784) Executing the query "ALTER INDEX [PK_activityLog] ON [dbo].[activityLog] REBUILD WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, SORT_IN_TEMPDB = OFF, ONLINE = OFF ) " failed with the following error: "Could not allocate a new page for database 'FA_PROD_SDDS' because of insufficient disk space in filegroup 'PRIMARY'.
Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. The statement has been terminated.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
The database 'FA_PROD_SDSS' is the one that I am having issues with.
Internal Query Processor Error: The Query Processor Encountered An Unexpected Error During Execution.
Nov 26, 2007
I am running a query on a SQL Server 2005 database and encounter the following error message
"Internal Query Processor Error: The query processor encountered an unexpected error during execution."
There is a join between a table on the 2005 database and another on a 2000 database. I have run DBCC CHECKTABLE and found no errors on the two tables.
Anybody with ideas?

What Is Being Stored In ASPNETDB.MDF -- It Consumes ~1/2 My Sites Space!
Mar 14, 2007Using VS2005, VB backend and javascript,
I have developed a relatively simple site - its got a few (12) simple aspx pages but its mostly client side javascript. Keeping disk storage costs down is a big concern with this my site. The disk usage for the site is ~24M. Since this was larger than I expected I started inspecting the files comprising my site and found that the "ASPNETDB.MDF" in my "App_data" folder is consuming 10.2M by itself. The thing is that site only has a few pages with calls to SQL Server - but I never did anything (that I know of) with ASPNETDB.MDF. Through VS2005, I opened up the MDF file and poked around, everything that I looked at was empty (NULL).
So my questions are:
What is causing the ASPNETDB.MDF to consume 10.2M even thought I can't see any data stored in it?
Is there anyway for my to reduce the size of this file? If so, how?
Can someone give me some pointers as to where to read up on what the ASPNETDB.MDF does?

Error: 8624 Internal Query Processor Error: The Query Processor Could Not Produce A Query Plan.
May 24, 2007SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).
SQL In-Memory :: Table Memory Optimization Advisor Validation Passed But Cannot Migrate
Jul 13, 2015I am looking to test this feature - and the "Transaction Performance Collector" has recommended me a table to port to In-Memory OLTP.
I have now tried the "Table Memory Optimization Advisor" tool.
After a couple of tweaks to the table design - the tool is now passing validation but the tool is not allowing to progress to the next step:
Could it be down to not having enough memory? But would this not show in the advisor?

AWE/Lock Page In Memory Drawbacks? Min/Max Settings, Memory Issues
Oct 11, 2007I've been researching AWE to determine if we should enable this for our environment.
Currently we have a quad core box with 4 gb of RAM (VMware). OS: Windows 2003 std, SQL Server 2005 std. 3GB is not set but will be as soon as we can perform maintenance on the server.
I have read mixed feedback on AWE, either it works great or grinds you to a hault. I would assume that the grinding to a hault is due to not setting the min/max values correctly or not enabling the lock page in memory setting.
We only have one instance of SQL on the server and this box won't be used for anything else aside from hosting SQL services. We do plan on running SSRS off of this server as well.
1. Will running SSRS and enabling AWE cause me problems? Will I have to reduce the max setting by the SSRS memory usage or will it share and play nice?
2. How do I go about setting the Max value? Should it be less than the physical RAM in the box? Right now its set to the default of 214748364, even if I don't enable AWE should this default value be changed?
3. It seems that even at idle the SQL server holds a lot of memory and the page file grows. If I restart the process in the morning, memory usage in taskmon is at 600mb or so. By the end of the day, its up around 2gb. How can I track down whats causing this, should this even concern me?
4. The lock Page in memory setting worries me. Everything I've read on this seems to give a warning about serious OS and other program support degradation. In some cases to the point where they have to restore the settings on the server before they can bring it back up. What are your thoughts on this.

Would Max Memory Including SSIS And SSAS Memory
Mar 27, 2008Hello, I understand that we should use SSMS -> Server Properties -> Memory to put a cap on the SQL server memory usage, therefore it gives some space memory for OS, this is based on the fact if the max memory is not specified, SQL will use whatever available memory and eventually crash the system.
My question is that when a server has SSIS and SSAS services installed along with the SQL service. Would the max memory setting covers the SSIS and SSAS memory usage, or the SSIS and SSAS has to shared the memory with OS?
Thanks,

Memory Issues, SSIS Package Out Of Memory Help
Dec 6, 2006I am running Visual Studio 2005. I have an SSIS Package which is consuming a huge amount of memory. During the execution of the package the memory keeps increasing. Until finally i get an Out of Memory exception. I have run this package using dtexec, and in the BIDS. No difference. I do have some script components and have added some code to get the assemblies in the current appdomain. I do see that one particular assembly is increasing on every loop. VBAssembly every time it hits the script component is increasing by 6, and along with it the memory is climbing. What is this VBAssembly being used for is there an update to SQL Server Integration Services that I need?
Thanks! Aaron B.
Sql Server 2000 Using Less Memory After More Memory Added
Aug 22, 2007sql server 2000 is running on windows server 2003 ... 4gb of memory on server .... 2003 was allocated 2.3gb nd sql server was allocated (and using all of it) 1.6gb for total of approx 4gb based on idera monitor software ... all memory allocated betweeen the OS and sql server .... then 4 more gb of memory added for total now of 8g ... now idera monitor shows 1.7gb for OS and 1.0 gb for sql server ..... 'system' info shows 8gb memory with PAE ... so I assume that the full 8gb can now be addressed .... why are less resources being used now with more total memory .... especially sql server ..... i thought about specifying a minimum memmry for sql server but i amnot convinced that would even work since it seems that this 1gb limit is artificial .... it it used 1.6 gb before why would it not use at least that much now ??
thank you

I have to assume that this is not that uncommon of an activity, and the OS and SQL Server should be fine.
Basically we are contemplating upgrading our quad processor (Xeon Cranford's) with four dual cores.
