I am using the following Connction string in web.config in asp.net
application
<add key="ConnectionInfo" value="Data Source=MyServer; Min Pool Size=5;Max
Pool Size=100; Connect Timeout=120; Initial Catalog=TestDB;User
ID=sa;Password=******;"/>

Application is running fine but after couple of days I got the follwong
exception on login page but there is no error and all connection are closed
properly. Then I reset IIS server & site come up again after IIS reset

The Exception is

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.
