Yes, thanks for that. Good point. I checked the logs, and minutes before it crashed I can see below in the logs. Seems like either a GPU error or out of memory error.
No idea what tracker-miner-f is by the way.
It also shows a massive list of processes with their memory usage.
This goes beyond my knowledge :(
