asp.net application running in production is crashing

I have an asp.net application written using a combination of technologies such as Asp.net MVC,WebAPI,SignalR etc and it is crashing almost everyday randmoly. I get this message logged by IIS in the event logs

Faulting application w3wp.exe, version 6.0.3790.3959, stamp 45d691cc, faulting module kernel32.dll, version 5.2.3790.4062

I understand that we can use some kind of CLR profiler to get the crash analyzed but even that requires approval and we had a situation where the profiler was causing real slowness to our application as the application is very chatty(Hence signalR) .So I am looking for a solution with minimal impact on runtime but would like to figure out the root cause of the crash.

WER helped me troubleshoot this issue.Enabled crash dump using WER

Windows Registry Editor Version 5.00
�
 
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\w3wp.exe]
"DumpFolder"=hex(2):63,00,3a,00,5c,00,64,00,75,00,6d,00,70,00,73,00,00,00
"DumpCount"=dword:00000002
"DumpType"=dword:00000002

And this created an hdmp file and I was to get this analyzed using debugdiag and windbg to find out the issue. There was a stackoverflow exception happening and caused the application to crash.

Are you using dedicated application pool for your app ? if not, you can try to add new application pool and configure it for your application.
