ASP.NET

On the main production server, the IIS worker process crashes sometimes. From the event viewer I get the following information.

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8 Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319 Exception code: 0xe053534f Fault offset: 0x0000b9bc Faulting process id: 0x%9 Faulting application start time: 0x%10 Faulting application path: %11 Faulting module path: %12 Report Id: %13

This happens randomly on the prod server and I have not been able to recreate this crash anywhere else. This was happening on IIS 6, and we recently moved to Windows Server 2008 and IIS 7.5 and the crash happens there as well.

How to go about finding the root cause of this?
