Hi, Server farm is 1 SQL , 1 Application and 1 WFE server. Recently SharePoint site is becoming slow at different timings. During the same time the WFE server eventvwr is showing " ISAPI 'C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected '. " in Application logs and " A process serving application pool 'partnerweb' exceeded time limits during shut down. The process id was '6704' . " in System logs. whenever these warnings occurs site response is slow. There is no help from SharePoint and IIS logs to figure out the problem. Please help on finding the root cause for these DeadLocks. http://support.microsoft.com/kb/828222 other than this link provide me useful info. ------------ v235
