It comes up periodically. It happens to me. And your are right,
unloading and reloading usually fixes it. I have not tried just using
update slots. The next time it happens, I will try that first. I just
installed 2.4.2 yesterday, and removed all my tweaking, so I can see
if/how 2.4.2 behavior changes. I was using 2.4.1.
But it would be nice to know why bacula does not like the volume when
this happens, even if it is not a bug in bacula.
