When it came back up we immediately started getting this error from the server DATE/TIME: 2/27/2014 3:09:31 PM DESCRIPTION: The SQL Server performance counter deadlocks sql server 2005 'Number of Deadlocks/sec' (instance 'Database') of object 'SQLServer:Locks' is now above the threshold of 1.00 (the current value is 2.00). COMMENT: (None) JOB RUN: (None) We ran the DBCC TRACEON (1204) command and have watched the log's but it's not reporting any deadlocks. Any idea what could trigger this to just go off? We are getting the alert every minute yet can't find any actual deadlocks. Edit: I should add that before this reboot we had never received this error Edit 2: We used SQL Server Profiler as well to look for deadlocks, let it run for 5 minutes over which we received 5 error alerts and when we checked the details we had NO deadlocks found. Edit 3: March 06/2014: Ran the query and it worked, but it reports what our other details have said that we have no locks we where still getting the error above the whole time. Thanks again for all your help! Edit 4: March 06/2014: I ran the query and here is a sampling of the result set, I will admit I am not exactly sure what I am looking at here, that is to say I am not sure if it shows me something that I ca

to Track Down Deadlocks Using SQL Server 2005 Profiler 20 June 2008How to Track Down Deadlocks Using SQL Server 2005 https://www.simple-talk.com/sql/learn-sql-server/how-to-track-down-deadlocks-using-sql-server-2005-profiler/ ProfilerIt is irritating, sometimes alarming, for the user to be confronted by the https://blogs.msdn.microsoft.com/bartd/2006/09/08/deadlock-troubleshooting-part-1/ 'deadlock message' when a deadlock happens. It can be a tiresome business to prevent them from occurring in applications. Fortunately, the profiler can be used to help DBAs identify how deadlocking problems happen, and indicate the best way of minimising the likelihood of their reappearance. 303 30 Brad McGehee A sql server Quick Introduction to Deadlocks Deadlocking occurs when two or more SQL Server processes have locks on separate database objects and each process is trying to acquire a lock on an object that the other processes have previously locked. For example, process one has an exclusive lock on object one, process two has an exclusive lock on object two, and process one also in sql server wants an exclusive lock on object two, and object two wants an exclusive lock on object one. Because two processes can't have an exclusive lock on the same object at the same time, the two processes become entangled in a deadlock, with neither process willing to yield of its own accord. Since a deadlock is not a good thing for an application, SQL Server is smart enough to identify the problem and ends the deadlock by choosing one process over another. It does this by killing one of the processes (usually the process that has used the least amount of server resources up to this point) and lets the other one to continue to run. The aborted transaction is rolled back and an error message is sent to the application. If the application is deadlock aware, it will resubmit the killed transaction automatically and the user may never know the deadlock happened. If the application is not deadlock aware, then most likely an error message appears on the application's screen and you get a call from a disgruntled user. Besides irritating users, deadlocks can us
8, 200681 0 0 0 A deadlock is a circular blocking chain, where two or more threads are each blocked by the other so that no one can proceed. When the deadlock monitor thread in SQL Server detects a circular blocking chain, it selects one of the participants as a victim, cancels that spid’s current batch, and rolls backs his transaction in order to let the other spids continue with their work. The deadlock victim will get a 1205 error: Transaction (Process ID 52) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. A deadlock is a special type of blocking scenario, but blocking and deadlocking are not the same thing. Sometimes we have people report that they are experiencing "deadlocking" when they are really only seeing blocking. With very few exceptions, deadlocks are a natural side effect of blocking, not a SQL Server bug. The typical deadlock solution is either a stored proc/app code tweak, or a schema/indexing change. Here’s how to troubleshoot deadlocks. These steps apply to most deadlocks, and they’ll allow you to resolve many of them without even having to dig into query plans or other nitty gritty details.What’s that? You like digging into query plans, and have nitty grits for breakfast every morning? OK then, we’ll look at a deadlock scenario from the inside out a bit later. But first, here are the basics: Turn on trace flag 1222 with “DBCC TRACEON (1222, -1)” or by adding “-T1222” as a SQL startup parameter. This trace flag is a new trace flag in SQL 2005, a much improved version of the tried-and-true -T1204. If you’re running SQL 2005, you should be using 1222 instead of 1204 unless you have deep-seated masochistic tendencies. Alternatives to 1222: If you are using SQL 2000 or SQL 7.0, you’ll have no choice but to fall back on the older -T1204. There’s a “Deadlock graph” Profiler trace event that provides the same info as -T1222. Feel free to use this instead of -T1222 if you’re on SQL 2005. But don’t waste your time with the “Lock:Deadlock” and “Lock:Deadlock Chain” trace events that are in SQL 2000, as they provide an unacceptably incomplete picture of the deadloc
