Thank you Kees,
It would be most helpfull if you can answer my questions in the mean time?
– is swap enable or not on your linux OS ?
– is your linux mint fully up-to-date ?
– is the OS running out of memory befor the crash?
The more information you provide the faster I can get to the bottom of this ;-) and I really want to solve this.
Regarding a virtual computer, whole bank networks (which require the best stability and security) run on virtual computers/servers, because it really works like regular computers only with shared hardware resources. So something must speak for it to work properly I would think.
