Getting SQL Server Deadlock Error - How Do I Work Around?
Mar 27, 2007
I have some ASP.NET C# code which executes a stored procedure in SQL Server via the SqlCommand and SqlConnection classes.
One of the stored procedures that gets executed is giving the error: "Transaction (Process ID 272) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction." This only happens occassionally.
Is there a way to get around this in my ASP.Net application? One thing I tried is ensuring that no 2 users entered the stored procedure concurrently:object synclock = new object() ;
lock (synclock) {
// execute SQL stored procedure
...
} This did not solve the problem, and I'm not even sure if that is the correct implementation to ensure sequential execution of the stored procedure.
Hi, I have no idea what i'm doing wrong: Tried to gather more detail information about Deadlock (error # 1205) set the trace flag 1204 - ON (tried 1205 - ON as well) nothing happend, still the same message outgoing "Your transaction (process ID #13) was deadlocked with...." with no any detail. If anybody met the same problem before, HELP please.
Maybe the information goes to some place other than Error Log file?
I want to set an alert for a specific table whenever an event hascaused a deadlock to occur on the table.I understand how to set up an alert. But I don't know which errornumber to use for the New Alert error number property for a deadlock.Or how to specify a deadlock on a specific table.Thanks,DW
We have lately experianced a strange problem with our SQL Server 2005 x64 (SP2) that is NOT consistent but when it happens it happens on the same time.
Almost every night at 03:30 one of our databases (not all) seems to be down or locked. When i have a look at the order table in this database I can see that we have stopped recieving orders after 03:30. Two hours later (05:30) I can see the following error each minute in the error log until we reboot the server:
All schedulers on Node 0 appear deadlocked due to a large number of worker threads waiting on LCK_M_IS. Process Utilization 0%%.
As we have a maintenance job running at 03:30 it feels like this is the problem. The job performs the following tasks: "Check Database Integrity -> Rebuild Index -> Reorganize Index"
When i look at the history of the job it looks like it's not completed and only the "Check Database Integrity" task was runned. No error message here either.
Also when i look in the error log i can see that the Maintenance job is started but never ended. Worth to notice is that I get the follwoing info in the log after the start-message:
Configuration option 'user options' changed from 0 to 0. Run the RECONFIGURE statement to install.
Also, when i run this job manually daytime it works great!
Anyone having any idees on this? Is it possible to track this even more? I'm tired of restarting the server 03:30 in the morning =)
Is there a way to send out an email woth deadlock information (victim query, winner query, process id's and resources on which the deadlock occurred) as soon as a deadlock occurs in a database or at instance level?I currently has trace flag 1222 turned on. And also created an alert that send me an email whenever a deadlock occurs. but it just says that a deadlock occurred and I log into sql server error log and review the information.
I received the following error message when run the query,
Server: Msg 1205, Level 13, State 61, Line 1 Transaction (Process ID 61) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
I am getting quite a few deadlock errors where both sessions aretrying to execute sp_execsql according to the the trace information inthe error log (see below). The database is being asscessed by anapplication written in .NET, as well as a few people using QueryAnalyzer. This seems to be happening relative randomly - can't pin itto any specific circumstances. Any thoughts would be appreciated.RID: 8:1:617:37 CleanCnt:1 Mode: X Flags: 0x2Grant List 1::Owner:0x3738dbe0 Mode: X Flg:0x0 Ref:0 Life:02000000 SPID:55ECID:0SPID: 55 ECID: 0 Statement Type: CONDITIONAL Line #: 47Input Buf: RPC Event: sp_executesql;1Requested By:ResType:LockOwner Stype:'OR' Mode: S SPID:52 ECID:0 Ec:(0x4AC4D570)Value:0x23297b80 Cost:(0/12C)Node:2RID: 8:1:267:91 CleanCnt:1 Mode: X Flags: 0x2Grant List 0::Owner:0x3efae340 Mode: X Flg:0x0 Ref:0 Life:02000000 SPID:52ECID:0SPID: 52 ECID: 0 Statement Type: CONDITIONAL Line #: 115Input Buf: RPC Event: sp_executesql;1Requested By:ResType:LockOwner Stype:'OR' Mode: S SPID:55 ECID:0 Ec:(0x483FB570)Value:0x37c0e060 Cost:(0/138)Victim Resource Owner:ResType:LockOwner Stype:'OR' Mode: S SPID:52 ECID:0 Ec:(0x4AC4D570)Value:0x23297b80 Cost:(0/12C)
We just upgraded to SQL Server 2005 from SQL Server 2000. The DB was backed up using Enterprise Manager and restored with SQL Server Management Studio Express CTP. Everything went as expected (no errors, warnings, or any other indicator of problems).
The DB resides in a DB Server (Server1) and the application we are running is a Client/Server system where the AppServer resides on Server2.
During the application's operation all read, create, and delete transactions work fine but no update works. When viewing details in Trace Log I see this message after attempting any update:
Could not find server 'Server1' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. (7202)
guys, I have a stored procedure which gets called by ASPX page and it inserts, updates data into different tables. originally, I had a issue that if error occured, it would not rollback all the data so i used transaction around it. now, once in a while I am getting this error "System.Data.SqlClient.SqlException: Transaction (Process ID 181) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction". I don't know how this error occurs and how do I prevent it. please help. transaction is as follow. BEGIN TRY BEGIN TRANSACTION // t-sql codes to insert update multiple tables COMMITEND TRY BEGIN CATCH if (@@TRANCOUNT > 0) --error ROLLBACK declare @errSeverity intselect @errMsg = ERROR_MESSAGE(), @errSeverity = ERROR_SEVERITY() RAISERROR(@errMsg, @errSeverity, 1) END CATCH
I used veritas to backup MsSQL 2000 database server but I often encounter backup fail error due to the deadlock in the database. May I know how to reduce this problem?
I heard there is a method to control the database deadlock timeout. If we set a lock timeoutvalue, will it reduce the chance of deadlock to happen? Is there any disadvantage of doing that?
If I were not wrong , we can set the lock_timeout value using the syntax "SET LOCK_TIMEOUT milliseconds" Is that true? But Do we have to have to run this command for every database? What is the normal milliseconds value?
I have a Stored Proc that is called by a SQL Job in SQL Server 2000. This stored proc deadlocks once every couple of days. I'm looking into using the @@error and try to doing a waitfor .5 sec and try the transaction again. While looking around google I've come across a few articles stating that a deadlock inside a Stored Proc will stop all execution of the stored proc so I will not be able doing any error handling. Is this true? Does anyone have any experience that could help me out?
I know the best solution would be to resolve why I get a deadlock. We are currently looking into that but until we can resolve those issues I would like to get some type of error handling in place if possible.

Hi Guys. I just want to ask some insights on SQL Server Deadlock and what is the best way to handle deadlock in asp.net? Or something like a Try... Catch.. statement to handle the error? Please advice. Thanks in advance.
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?
I'm investigating my production server because there appears a deadlock every day. So, in SQL Profiler, I use the the Deadlock graph to capture the trace in a file.
When I click on the textdata to see the graph an error appears: - Failed to initialize deadlock control. Cannot find process victim in process list.
I also get the following error from another deadlock: - Failed to initialize deadlock control. Object reference not set to an instance of an object.
I stopped my trace, so this can not be the problem.
Does anybody knows why I can't see the graph?
I also captured the trace in a table and then used the following query to see it in xml: select convert(xml,textdata) from TableName
I have a framewrok that runs tests and keeps updating the status of the tests to the DB. They are approx 20 tests whose status will be updated simultaneously. Recently i have seen the follwoing error
{"Transaction (Process ID 84) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction."}
I have one situation. I need to find out the processes which are all in deadlock state. I my figure out that SQL server maintains the process details in sysprocesses table.
Can any one please help me, Whether this is the table which contains deadlock details. If not where are they stored and How to kill that process ?
Below query. its getting more time to exec and got deadlock. So, query to avoid deadlock.

And how did I get 4 errors? - I only set my script task result to failure
Dead lock is coming in select query in application because of index. It is identified after enabling trace in database and identified by reading deadlock xml file. After index removal, deadlock is not coming in same query. But it is affecting query's performance slightly. Is it correct way to remove index if dead lock is coming because of index?
There are a series of traces of transactions for essentially the same units of work. Each includes a retrieving the same table "Select" from the database. The first 4 transactions ran concurrently. The last one ran about 7 minutes later with no other concurrent transactions.
The elapsed times for the database accesses for each of the first 4 is significantly higher than the last one. Can you think of any database optimazation that might improve this?
Are there any utilities available than can be used for stand-alone testing of SQL Server database performance? E.G. they would measure response time for reading/writing large/small amounts of canned data once/multiple times with concurrent/nonconcurrent access.
SQL Server Database is on 2000.I am not sure about the ISOLATION level in the Java code.
Basically I am new to SQL Sever....Please ans the above questions and provide me the direction to proceed on these questions
We have around 5 SP’s which are inserting data into Table A,and these will run in parallel.From the temp tables in the SP,data will be loaded to Table A. We are getting deadlock here.No Begin and End Transaction used in the stored procedure.
I'm trying to use schedulled task to automate restore and i keep getting the error database in use, it is set to dbo only and single user, and it has me as the user that has the lock, i have tried to kill it but it won't go, i have even started and stopped the server. any ideas?
I'm unable to get an alert to fire for Error 2627, Primary Key Violation. I have followed BOL's instructions for creating an alert, which appears to be nearly identical to 2000, however the alert will not work. I can see the error number in a Profiler trace along with the Severity number. I've also tried creating alerts for other error numbers and had the same result. The BOL instructions are as follows:
To create an alert using an error number
1. In Object Explorer, connect to an instance of the SQL Server Database Engine, and then expand that instance. 2. Expand SQL Server Agent 3. Right-click Alerts and then click New Alert 4. In the Name box, enter a name for this alert. 5. Check the Enable check box to enable the alert to run. By default, Enable is checked 6. In the Type box, click SQL Server event alert. 7. In the Database name list, select a database to restrict the alert to a specific database 8. Click Error number, and then type a valid error number for the alert 9. To restrict the alert to a particular character sequence, check the box corresponding to Raise alert when message contains, and enter a keyword or character string for the Message text. The maximum number of characters is 100
i followed all the instruction to add the database of the adventure works to the database server. but when i attach the database from the managment sql server this error comes
Couldnt find row in sysindexes for database ID 8, object ID1 ..........etc
and couldnt open new database 'adventureworks'. create database is aborted.
please i need a qucik help. cuz i tried the msdn and i failed.
I€™m importing a Flat file (delimited text) into a sql server database table and trying to trap any import errors in another output Flat file.
I create a Flat File Source task. After tweaking the task, the Source €śError Output€? tab shows all the input columns and all €śError€? and €śTruncation€? values are set to €śRedirect row€?
Next I add a €śSQL Server Destination€? task and connect the Source green arrow to it.
Finally I add a Flat File Destination task (error Output task), connect the Source red arrow to it, click €śOK€? in the €śConfigure Error Output€?, and finally add a connection manager to the Error output task. When I look at the Mappings tab of the Error Output file it shows only three available input columns: €śFlat File Error Output Column€?, ErrorCode, and ErrorColumn
I€™m not sure where they came from but that info is not very useful to me. I want to know which line the error occurred on as well as the bad column(s). If nothing else, I need to see at least the actual row that was bad. How can I get that information?
Good Morning, I've been searching through all the tutorials and questions, have tried many things. I am still getting "[SqlException (0x80131904): An error has occurred while establishing a connection to the server.

I'm getting extremely frustrated, and would just like the login portion of this website to start working before my boot ends up through the computer. Please help, lol, thank you.
Been doing some research after getting this error: Microsoft OLE DB Provider for SQL Server error '80040e14'
Cannot create a row of size 8297 which is greater than the allowable maximum of 8060.
And realised that my nice responsive varchars had a maximum total size. so I changed them for 'slower' text data types. but my DB still won't allow any more input.
has the limit been reached now regardless of what I change or can I rebuild the DB to recover the space or something?
Hi Everyone, I'm having some trouble with the below trigger. When I add a row of data either manually or using an INSERT query, it just doesn't do anything. It doesn't provide any error messages either. This makes me think that it's aborting the operation because rowsAffected are 0 or some other simple error. My row manipulation code could be suspect also. This is my first time writing a trigger or using T-SQL for that matter. What I'm trying to do is to have the trigger add +1 to the Iter field of all rows where BouleID is equal to the BouleID of the row being inserted. So let's say I have the following table:
Now, if I insert a row with BouleID = A01 and Current Location = Polishing, I want the Iter field of all previous rows to iterate by +1 and this new row to have Iter = 0.
I am using SQL Management Studio Express, and SQL Server Express.
Any thoughts on anything wrong with my selection code and iteration code? Could I adapt this to handle more than one row by using a GROUP BY BouleID somehow?

I have had the same Error 29506 that a lot of people are having when installing SP2 for SQL 2005. I've tried the install with myself (a Domain Admin), local Administrator, cascaded full rights down the entire file system structure and still not luck. One thing I'm wondering if it is hanging me up is that all of my databases and logs are not on C:. They are on LUNS on a NetApp SAN (Data is on M: and Logs is on L:). Even the system databases (Master, Model, etc.) are on the LUNs. The error logs referenced permissions to the data directory under the default installation path on C:. Anyone else have this problem? Got a fix? I really don't want to migrate all of my data back to the local machine, apply the patch, them migrate back. Surely this SP should be able to read the data location from the SQL engine. And surely others have their databases on SANs.... I'm at a loss.
