I am facing the same problem every day in the morning time.
1)Server time out 2)System.InvalidOperationException: 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.
i am having this exception daily at 4-5am in the morning. i tried recycling pool one day at 2am. but still the same problem comes at 4-5 am. then it solves when i recycle the pool after exception occured. is it really due to non availability of connections or network related problem.
please help thanks.
