With version 1.38.9 this *should* not be happening. From the messages, it
looks like the SD realized that something was wrong then tries a last resort
attempt to straighten things out by asking for operator intervention. With
the little information here, there isn't much to go on. What I suggest is
the next time it happens, provide the Job reports for all jobs involved (the
one that has the Volume and the one that wants it) as well as the output from
a "status storage" command.
Why do you says that this "used to be a problem ..."? It sounds like it was a
problem (true), but that it went away, and now it has come back. If that is
the case, what has changed between the time it went away and now?
