pool

Hello,

I have problem identifying which page/page/function locks whole IIS server.

Out of the blue whole w3wp.exe jumps to CPU 90-98% usage. I have created 3 different application pools to see which w3wp.exe service locks the processor but I am unable to find out this information.

I can only see that 2 of 3 services have 0-5% usage and one is jumping around 90-98% after some while. I think some process/function/redirect/sql is doing this but I would like to eliminate it. So far I am not even able to find the source of the problem. On my local development machine with VS2010 everything works like charm and I am unable to replicate problem.

The server is windows 2k3 web server, sql server 2k5 and .net 4.0

Thank you for your help, links or any information on this issue.
