Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

The server has always been 14.04 LTS, so no big kernel upgrades. There was however an installation of a new VM machine ongoing. Perhaps something in that caused the host server to crash.

Do you have a way to reproduce the crash, or was it a one time event?

The crash has occurred only once. Unfortunately, I don't know how to reproduce the problem. The server had been running with high computational load for several days. Perhaps that was contributing to the problem.
