Hi
I am running a web application having 500-600 users at a particular time on sql 2000 and ASP.NET 2005.
generally it works ok but suddenly it goes down. when i check progress tab of Task Manager it shows 0 % CPU usage.

when i restart sql service (through SQL Agent) then software begins running normally.

i don't know why this is happening.

pls guide me to come out of this problem.

Well, could be someone of these users is locking some critical data, blocking everybody else from processing their stuff.

Attached you can find my SP_dba_whoblocks sproc which I use on all ( not that many ) of our remaining SQL2000 instances.
