> Googling around lead me to old jessie bugs (kernels 3.16): > https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1423672 > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=818502#22 Seems the bug is really this. I've increased the RAM of the problematic VM, and FS corruption deasppeared. Effectively, all other VMs have plently of free ram, this was a bit full. I know that PVE 4.4 is EOL, but still i'm seeking feedback. For example, is a 'host' kernel bug, or a 'guest' kernel bug? Thanks. -- dott.
