You can not do anything from outside the program.

The message is clear: Value cannot be null , this is ether a bug, ether a bad configuration of your program.

One function is called with null value, and crash.

By the way, pool is not crash, just the page is not working.

According to this: https://connect.microsoft.com/VisualStudio/feedback/details/449469/transactedconnectionpool-bug-in-vista-server-2008-sp2

It's known bug with SP2 - I think the most simple work around is what Polchen wrote:

Disable connection pooling in the database connection string

Hopefully this string is inside configuration file and not hard coded.
