Ever since loading up nopCommerce on my Win Server 2008 box - I have started seeing daily reboots of my server. To the point where the server becomes completely unresponsive.
After reviewing the logs / dmp information I have concluded that there is code (maybe even 3rd party) being referenced in nopCommerce that is causing a memory access violation. I haven't been able to determine the culprit, but I believe I have found a solution. (hot fix from microsoft - the code will continue to be faulty).
The key to resolving the issue was the faulting module CLR.DLL. KB states the following:
The issue occurs because an object that is being referenced is dereferenced by the garbage collector in common language runtime 4 (CLR4). Therefore, an access violation occurs during garbage collection or when the application tries to access the released object.
Hot Fix: (if this doesn't fix it, i'll reply back here)
