IIS app pool is shutting down when connecting to Oracle DSN?

I am trying to connect to the Oracle database using the DSN in my web application and when I browse the site the app pool crashes. The DSN is set up correctly I think because when I hit Test connection it successfully connects. When I looked at the Event viewer If found the Application Error with below details,

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8
Faulting module name: oracommon11.dll, version: 11.2.0.1, time stamp: 0x4bb5eab3
Exception code: 0xc00000fd

I found this pretty similar but it is similar not exactly my exception. So I am confused. Any help would be great to resolve this issue.
