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

* There are no erros in my application log(log4net)
* There are no other logs in the application and system logs
* I cannot install any tools or profiler in the production server as it requires many levels of approvals and privileges.

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.
