We had huge delays on our storage system affecting the mongo performance.
We are still investigating the root cause of our problems. It is possible that mongodb was not able to write the data to the disk for around 5 minutes.
The mongodb process crashed with an unhandled exception.
I've attached the minidump and the exception:
