Crash
Verify if they process is crashing using Application Crashes detector
Enable Crash Monitoring to collect a memory dump o crash
A crash dump will open on the context of the thread that caused the crash. This case, thread 32.
First thing we always check in the dump is the CLR version and establish if we are in a supported scenario.
Looking at the call stack of thread 32:
We see the same method called over and over making the stack to overflow.
Checking code we can see the recursive call that filled the stack.
