Rerun the transaction. I am getting this error randomly when one of my websites gets busy. I know roughly which sets of tables sql server 2008 it is happening on but in my experience with other programs I normally get the SQL returned where the deadlock is happening. Is there a flag I should turn on to allow this to happen? I will try and debug the deadlock itself as a seperate issue as this is my main question for now. I am using SQL Server 2008 Standard Edition. sql sql-server-2008 deadlock share|improve this question asked Jan 13 '12 at 13:22 webnoob 2601311 migrated from stackoverflow.com Jan 13 '12 at 16:59 This question came from our site for professional and enthusiast programmers. Are you able to restart the service? If you are able to bounce the service, you can add add trace flag 1204 to your startup parameters to log the details of the deadlock to the SQL Server log. > 1204: Returns the resources and types of locks participating in a deadlock and also the current command affected. > >Scope: global only –Tevo D Jan 13 '12 at 13:49 1 Use the configuration manager.

Facebook Twitter LinkedIn YouTube GitHub Capturing Deadlocks in SQL Server June 11, 2014Jes Schultz Borland20 comments What's a deadlock? Well, let's say there's a fight going on between Wonder Woman and Cheetah, and, in the same room, a fight between Batman and Mr. Freeze. Wonder Woman decides to help Batman by also attempting to throw her lasso around Mr. Freeze; Batman tries to help Wonder Woman by unleashing a rope from the grappling gun at Cheetah. The problem is that Wonder Woman already has a lock on her opponent, and Batman has his. This would be a superhero (and super) deadlock. When a deadlock occurs in SQL Server, two or more tasks are running and holding locks on data. Then, each task requests to lock the data the other task is already holding. Both tasks wait for the other to give up. Neither does. SQL Server could let this showdown continue indefinitely, but it won't. It picks one task - usually, whichever will be the least expensive to roll back - as the victim, and that task is killed. How do I know if it's happening to me? You might notice slowness in your application. Users might complain about slowness or error messages. And, you'll see a message in the SQL Server Log that says "Transaction (Process ID 103) was deadlocked on resources with another process and has been chosen as the deadlock victim." Your server has encountered a deadlock. How can I capture more information about it? You have several options: you can enable a trace flag to write more information to the log, you can capture deadlocks graphs using Profiler or Extended Events, and you can track the number of deadlocks occurring using Performance Monitor. Use trace flags to write to the log Two trace flags can be enabled to capture more information in the log: 1204 and 1222. 1204 lists the information by node; 1222 lists it by process and resource. You can enable both simultaneously. To enable the flags, use
