I have setup a SQL alert that email's me if deadlocks occur. I recently
started getting flooded with alot of emails(see below) with deadlocks. The
current value does not drop back down, it remains at 4 until I restart the
SQL server. This has happened once in the past before, about 3 weeks ago.
We fixed it by restarting the server. I have DBCC OPENTRAN on all databases
and there are no active transaction open. Perfmon shows that I have 0
deadlocks but still I get these emails. Turning trace 1204 also shows me 0
deadlocks occurring. Can someone help me.

Deadlock
In a high traffic environment, deadlocks eventually occur as number of data processes increase. How can deadlocks be avoided, minimized and resolved. Please kindly provide scenario examples and samples of T-SQL code. Thanks much.
Check out this previous thread on deadlocks:http://forums.asp.net/862097/ShowPost.aspx. You might find something in there to help you, in particular this link:Tips for Reducing SQL Server Deadlocks.|||In your previous post, you said:These 3 suggestions have all but eliminated deadlocking for me:
-- Keep transactions as short as possible
-- Reduce lock time
-- Consider using the NOLOCK hint
Did a full combination of the above eliminate deadlocking or not?
Please advise how to implement the 2nd and third suggestions with sample T-SQL code.
Thanks much.

For my particular situation, yes, the above eliminated the deadlockproblems we were experiencing. #1 and #2 were for me the samething -- using transactions as late as possible and finishing them asearly as possible reduced the lock time and went a long way to reducingcontention. For the NOLOCK hint, this is how you use it:
SELECT someColumns FROM myTable WITH (NOLOCK) WHERE someConditionSee also:SQL Server Lock Contention Tamed: The Joys Of NOLOCK and ROWLOCK.
