SQL Server Down: Process ID 121:406 Owns Resources That Are Blocking Processes On Scheduler 4.
Sep 11, 2007
The following question applies to SQL Server 8.0.2187 (2000 + SP4+916287/914384/898709/915065/915340):
We have now twice had an incident where the same SQL Server has stopped responding. The only workaround is to restart the SQL Service. After this occurs, the log is filled with the following messages:
2007-09-10 16:42:14.29 spid3 Process ID 197:320 owns resources that are blocking processes on Scheduler 1.
2007-09-10 16:42:14.31 spid3 Process ID 74:324 owns resources that are blocking processes on Scheduler 5.
We haven't been able to pinpoint a cause or reporduce the problem on a dev server. I've seen several posts about this issue online but not many answers. Does anyone have any advice on how to troubleshoot this issue?

Last night I received this error
Process ID 152:3 owns resources that are blocking processes on Scheduler 2.
When I did an BCC INPUTBUFFER I found it was sp_MSadd_repl_commands27hp which is doing the insert into MSrepl_commands has any else noticed and issue w/ sp_MSadd_repl_commands27hp blocking itself. At the time I had about 10 million records to move. I was using the default log reader settings so I was batching them in 500 chunk intervals.
I am wondering if any else has had problems like this? I basically see it whenever I move too much data through my replication server.
I found the followoing link http://support.microsoft.com/kb/319892
Sample Scenario
Client 1 connects to SQL Server.
Client 1 runs a Transact-SQL command that starts a transaction and performs data modification.
For example: begin tran
update authors set au_lname = 'test'
Client 1 becomes IDLE, shows up as sleeping, and awaiting a command with an open transaction in the sysprocesses system table.
Clients 2 through 255: Approximately 254 more clients log on to SQL Server and issue a SELECT from the authors table. These clients will all become blocked on the original update.
Client 1 tries to commit the transaction but it becomes queued because all the worker threads are tied up by clients 2 through 255.
I am afraid that I am seeing this more then I would like does anyone know a way to prevent this from happening?

I have upgraded a MS SQL database from 6.5 to 7.0. The database functioned fine in 6.5, now I have a table that is locking due to a blocking process. If I kill the process all is fine, but am trying to determine what is causing the process to hang. Has anyone experience any similar situations.

Hi,
I was trying to extract data from the source server using OLEDB Source and SQL Server Destination when i encountered this error:
"Transaction (Process ID 135) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.".
What must be done so that even if the table being queried is locked, i wouldn't experience any deadlock?

Hi there,
Currently using SQL Server 2000 (SP4). The following condition started occurring last week:
- Server has excessive blocking
- Majority of the processes are in runnable state
- Excessive blocking happens for a few mins. and repeats again during the day. Does not happen at night.
- Nothing on the server errorlog, profiler
- CPU averages 40 - 50% at that point of excessive blocking
Any help would be greatly appreciated.
Thanks.

Hi Folks,
I am having this table locking issue that I need to start paying attention to as its getting more frequent.
The problem is that the data in the tables is live finance data that needs to be changed and viewed almost real time so what I have picked up so far is that using 'table Hints' may not be a good idea.
I have a guy at work telling me that introducing a data access layer is the only way to solve this, I am not convinced but havnt enough knowledge to back my own feeling up. (asp system not .net).
Thanks in advance

Today I ended up in a situation where I had a process with total six "subthreads" (identified by different execution context) (seen in Activity Monitor). All of these had blocking=1. The server didn't function properly, I don't know the details of these problems, since I was not present at that time. We had to kill the processes. What is the process id 1, "RESOURCE MONITOR" in SQL Server 2005, seen in Activity Monitor? Is it fatal if some processes are blocking RESOURCE MONITOR? How can one end up in such situation, is it normal or a bug somewhere?
The server is a 64-bit Windows server having SQL Server 2005 SP1.
Yesterday I had a CLR stored procedure running on another server. The procedure uses System.Data.SqlClient.SqlConnection to access this server. The procedure started about 11.4.2007 22:22. The procedure created a connection to the SQL Server and created a select that should return 1,5 million rows. During fetching the rows (about after 800 000 rows) the procedure crashes to an error:"".NET Framework execution was aborted by escalation policy because of out of memory. " Naturally the procedure couldn't close the SQL Server connections, since it was forced to end.
The details if the processes as seen from ActÃvity Monitor (I only have screenshots so I can't copy-paste...):
The main process:
Process id: 69
status: suspended
open transactions: 1
command: SELECT
Application: .NET SqlClient Data Provider
Wait time: 578
Wait type: ASYNC_NETWORK_ID
CPU: 1375
Physical IO: 22
Memory usage: 2
Login time: 11.4.2007 22:22:05
Last batch: 11.4.2007 22:22:05
Blocked by: 0
Blocking: 1
Execution context: 0
Two "subthreads", there are five similar.
Process id: 69
status: suspended
open transactions: 0
command: SELECT
Application: .NET SqlClient Data Provider
Wait time: 35293046
Wait type: CXPACKET
CPU: 4875
Physical IO: 2214
Memory usage: 2
Login time: 11.4.2007 22:22:05
Last batch: 11.4.2007 22:22:05
Blocked by: 0
Blocking: 1
Execution context: 1
Process id: 69
status: suspended
open transactions: 0
command: SELECT
Application: .NET SqlClient Data Provider
Wait time: 35293031
Wait type: CXPACKET
CPU: 4875
Physical IO: 2210
Memory usage: 2
Login time: 11.4.2007 22:22:05
Last batch: 11.4.2007 22:22:05
Blocked by: 0
Blocking: 1
Execution context: 2
The rest three subthreads differ from the above by having different wait time, CPU, physical IO and execution context.

When I was trying to get my maintenance plans to work there were many processes I had to kill. These processes were killed over a week ago but they still list in the Current Activity | Process Info list. Under Command it says "Killed/Rollback". If I go into QA and run kill 65 with statusonly it says the process is complete. How do I get these processes off the list?

I have a test database for the end users to test their select queries for reports.
One of my users is writing queries that cause locking in the database. I killed the process last evening and they are in Killed/Rollback status but are still hogging 90% of the CPU resources for the past 12 hrs. I tried killing them several times but no go.
I know that the best way to clear of these processes is by restarting SQL Server. If that is not an option is there is any other way we can clean these processes?
Also the user running these queries has a read only and create view access to the database. From my experience processes that go into Kill/Rollback state after you kill them are processes associated with some update transaction. Since the user as far as i know is running Select commands would an infinite loop cause this ?
thanks

Imagine I set a begin transaction on table a and updating a row and not committed and not roll backed--first connection
From second connection I am selecting same table (obviously it wait until first connection commits/rollback based on my transaction level: my isolation level is read committed).
1. How do I know second connection is to waiting to first connection to complete.
2. If I want to select rows that are not locked by update process how do i need to do(ex:row 1,2,3,4 and 1 is locked by update process(exclusive lock) and i want to leave that and i need to select 2,3,4 records).

We are having a really big problem with a zombie process/transactionthat is blocking other processes. When looking at Lock/ProcessIDunder Current Activity I see a bunch of processes that are blocked byprocess 94 and process 94 is blocked by process -2. I assume -2 is azombie that has an open transaction. I cannot find this process tokill and it seems that this transaction is surviving databaserestarts. I know which table is locked up and when I run a select *from this table it never returns. Does anyone have any ideas as tohow to kill is transaction.Any help is appreciated.A. Tillman

I have a job that was running on the SQL Server every business day. Once I disabled the scheduler for a day or two and then enabled it again. Well, now every once in a while my scheduler disables itself. Is there any logical explanation of this phenomenon?

I need to know exactly what VBA lines Create and Destroy SQL ServerProcesses - i.e. those visible in Enterprise Manager under Management[color=blue]> Current Activity > Process Info.[/color]Why?I am experiencing strange behaviour with Processes that are createdwhen I create a DAO Database Object with the following line:Set m_ResDatabase = DBEngine.Workspaces(0).OpenDatabase(strDSN, False,False, strODBC)This creates the process as expected.However the following lines don't always close the ensuing Process:If Not m_ResRecordSet Is Nothing Thenm_ResRecordSet.CloseSet m_ResRecordSet = NothingEnd IfIf Not m_ResDatabase Is Nothing Thenm_ResDatabase.CloseSet m_ResDatabase = NothingEnd IfIf Not m_ResWorkspace Is Nothing Thenm_ResWorkspace.CloseSet m_ResWorkspace = NothingEnd IfIt seems as if SQL Server keeps hold of the first two Processes andthen will release any subsequent ones.Can anyone shed any light in this - or any good web pages where Imight find some answers?Regards Chris

I need a script or stored procedure to tell me who owns what jobs. I have something like 150 and one of my job creators is no longer with our department. His account (NT domain) is still active but he is no longer working with these jobs and they need to be owned by someone else. Is there an easy way to do this?Dale

We installed the Sql 2014 in Test server.
We observed frequently
"Process 0:0:0 (0x1e10) Worker 0x00000006B6D341A0 appears to be non-yielding on Scheduler 13. Thread creation time: 12906028806348. Approx Thread CPU Used: kernel 0 ms, user 0 ms. Process Utilization 13%. System Idle 84%. Interval: 70189 ms."
Is it better to run the profiler or performan counter?
What are the filters we have to select in the profiler to monitor the Sql server

Dear, Our ASP.NET scripts send SQL statements (as inline SQL or SP) to process the requested job. After the job execution, the process ID stays in the server and waits for next command with sleeping status.Since this process does not go away, next job adds another process and eventually, the server is overloaded with these processes and dies. How can I kill this sleeping processes?Regards,Echo

Hi
Wanting to know how do you detect and kill orphaned spid in SQL Server left behind by an XML service which was not completed normally. The client requests an XML service which open a connection, and due to network problem the client did not manage to call the another service which suppose to end the connection. Thus leaving behind in SQL Server orphaned spid which continue to hold locks. This created problem when the next user wants to access the resource.
The simplest way is to get all spid which are holding locks for more than a certan period and kill them. Is there a better way to actually detect orphaned spid?
Help much appreciated.
regards

But how do i check to find out which objects or tables that this login is associated with.

I don't even know where to begin looking... I have a page that loads multiple web user controls...
I know I use one connection object class that is used in all my objects when executing the query (calling Stored Procedures).
The problem is when the first page is rendered and each user control queries the database (SQL Server),
it eventually slows down. In my controls, I use a lot of repeaters and internal queries per each repeater item.
So I know it hits the database quite often.
Problem is when I look in SQL Server Enterprise Manager Process Info, I have multiple worker processes sleeping.
My first thought is ASP.net is creating a new session connection (process) to the SQL Server? Why? How?
What do I do to check either my code is creating the connection object properly. Thanks!

I have a table and a specific column inside this table. I know this table is being updated, by using sys.dm_db_index_usage_stats, I was able to determine this, by some process (stored procedure / SQL Job / etc), but the problem is, I am not sure what process is doing it.
How would I search our SQL Server 2008 database to find any process that manipulates this table / column (I only care about Inserts / Updates and Deletes, but do not really care for SELECT).

We've got a 3rd party application that periodically runs SQL commands throughout the day. We've been getting issues with this application showing a sql error:
Transaction (Process ID 71) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
In checking the processes on SQL Server, there were a lot, and process ID 71 was actually hitting a completely different database.
Is there a way to streamline how SQL Server handles processes, and what's the limit at any given time?
