I am getting "500 Internal Server" error while accessing my webapplication in SharePoint 2010. After some tracing I found that the actual error is :

"Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached"

After I perform IIS Reset everything works fine but only for few minutes. I have already tried following: increase the executionTimeout in web.config to 3600

  • edit all custom code to have dispose

  • change the Idle Time-out in IIS

  • Change the timeout value to 90 in SharePoint configuration DB connection string

This error has recently occurred, can any one suggest what possibly could be done here.

  • Did you tried restarting the Application pool and Stopping unnecessary pool from running? – Vishwas Goswami May 5 '15 at 10:31
  • What about server resources? Memory, free space, cpu? – luccio May 5 '15 at 10:37
  • 98% usage of memory of 32 GB – Ahmed Masud May 5 '15 at 12:28

As you said, if perform IIS reset then it work fine for couple of min/hour then goes down. this make sense as 98% usage of memory of 32 GB is alot, Couple of things to check.

  • why Memory usage is too high, How many App pool running on the server.
  • Try to stop unused App Pool and Unwanted services from SharePoint
  • If you have customization on your site then make sure no memory leaks in it.
  • check the Search service, if that is consuming all resources.
  • check the App Pool connection setting.
  • Check the Logs for more clue.
