JITDebugger kept appearing w/ StackOverflowException

Question

Hi everybody, Opening and login on the web page created by another person causes the JIT Debugger Dialog to appear with a message: An exception 'System.StackOverflowException' has occurred in ... and when you click No, the web page displays Server Application Unavailable. We are using domain accounts here. What user account to use, how to set which accounts to use? what rights do this account needs? I need help. Thanks in advanced. Web Page Message: Server Application Unavailable Application Log Message: aspnet_wp.exe (PID: 2212) was recycled because it was suspected to be in a deadlocked state. It did not send any responses for pending requests in the last 180 seconds. System Log Message: IIS start command received from user . The logged data is the status code. Note: Using Domain account to access local pc where the web application is stored. den2005
