[libvirt-users] domains paused without any obvious reason

i have a two node HA-Cluster with several domains as resources.
Currently it's running in test mode.
Some domains (all on the same host) stopped running, virsh list shows them as "paused".
All stopped at the same time (11th of may, 7:00 am), my monitoring system began to yell.
I don't have any clue why this happened.
virsh domblkerror says for all the domains (5) "no space". The days before the domains were running fine and i know that all disks inside the domain should have enough space.
Also the host is not running out of space.
The logs don't say anything sensefully, unfortunately i didn't have a log for the libvirtd daemon, i just configured that now.
The domains are stopped each day by cron at 10:30 pm for a short moment, a snapshot is taken, domains are started again, the backing file is copied to a CIFS server and if that is finished the snapshot is blockcommited into the backing file.
That's working fine already for several days. This cronjob creates a log and it's looking fine.
The domains reside in naked Logical Volumes, the respective Volume Group has enough space.
