Comments
 
In most cases, this event is caused by problems in the code behind the page causing the problem. If possible, isolate the various parts of code and identify the faulting one.

The event contains the error type and the error description returned by the code (the "Exception message" section). For example, the error message for the event used as sample here is:

Object reference not set to an instance of an object.

This is a typical programming error where a variable is referred to in the code without actually initializing it first.

The troubleshooting process should focus on that error message as it is the most relevant bit of information.

ME893664 describes a way to get notified for this type of errors.
