Invalid connection seems to stop w3wp.exe from working

[burnEF]

Hi,

we have a problem with our Intranet Web Application ( ASP.Net 4.0, dotconnect 6.50.244, oracle client 10g, IIS7, Windows Server 2008).

It seems that when a connection gets invalid the w3wp process continues to try to work with that invalid connection. Which results in permanent errors:

Exception message: The underlying provider failed to open
and
Message: Server did not respond within the specified timeout interval

Only restarting the app pool helps in this case.

Is there a way to force the provider to open a new connection?

Please try using 'Validate Connection=true;' OracleConnection connection string parameter.
