I'm experiencing 16.04.02 total crashes during night since 2 days.
i was able to see the error shortly -> vm ran out of memory. the vm was installed in january with 4GB RAM, after first crash i upgraded to 8GB. But when i start the VM Backup (veeam) the available memory is going down for 10-15 MB/s till 0 -> then crash
