Freeze on FreeBSD VM running in PVE 9

Interestingly, everything works fine for me on 7 pbs/pve combinations recently updated to latest. Only 1 (!) SLES12 instance experiences this problem every single day during backup.
If I start the backup job manually it seems to work fine...
Waitung for the patch while holding my breath ;)
 
Update: changing the fleecing setting didn't change anything, the backup crashed 50% into 3TB and the VM was unusable, I had to stop/start, which did not work at all.As all VMs concerned had the ballooning flag set, most of them to 50%. I removed this and all VMs started ok.
It seems there is a SLIGHT bug in the implementation....
 
Hi @ViennaTux ,
please share more details, e.g. the task logs with the errors and excerpts from the system journal around the time of the issue as well as the output of pveversion -v and VM configuration qm config ID. If you are not running into the issue with FreeBSD, but Linux, it might be a different issue.

While the VM is frozen what does qm status ID --verbose say? Again while the VM is frozen, to get a stack trace for debugging, use apt install pve-qemu-kvm-dbgsym gdb and then obtain run gdb --batch --ex 't a a bt' -p $(cat /var/run/qemu-server/123.pid) replacing 123 with the actual ID of the VM.
