I am getting Timeout expired Error while Migrating application to VS2005 to VS2008

Question

Message: 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.

Answer 1

I had this issue on my live website with millions of users.

I found two solutions and both worked for me.

1)Immediate solution:set Pooling=false in connection string.

2)Later I closed all connections in my code and set Pooling=true.
