Hi together,

i have a strange behaivor every third backup. The lxc container have round about 650GB (data).
2 snapshots and backups working fine, the third backup failed during the snapshot.

TASK ERROR: job errors

I stopped vzdump (vzdump --stop). If I try the next backup same result. I have to reboot the lxc container, better the complett host. In all other logs I can`t see anything.

How can I debug this behavoir? Any idea whats going wrong? It is only this lxc container (seperate backup job).

BR
