Well, it happened again on a different volume and a different VM.
This time a self heal process was started.
Why is this happening? there are no network problems on the hosts and
they all do have bonded 2x1Gbit nics dedicated to gluster...
Is there any information I can give you to find out what happened?
This is the only mention about heal in the logs:

The VM went down 1 1/2 hour before:
