Hi ALL

our testing environment  (liberty with ceph) has been running for a while
and everything was working properly.

There was a cinder volume error happened yesterday.

from volume.log, it is showing:

Seems cinder volume service got killed and restarted.

is there any suggestion to avoid this error?
