Yes, you are right, I was confusing a SIGHUP with a SIGTERM. SIGHUPing Bacula is never a very good idea. Depending on what version of Bacula it is, it will most likely crash. If I am not mistaken, so far there are no reported crashes against version 1.38.11. > > > I don't understand why any process is sending HUP signals to Bacula when it is > > cycling logs.

If you are talking about cycling a Job report log file as defined in the Messages resource, then there is probably no need to SIGHUP Bacula as it opens and closes the log file on a Job by Job basis, if I am not mistaken. > > Additionally, this still seems to be a bug (even if it won't be affecting > me any more) since the director does not exit when hupped, but instead > freezes. > > I've done several searches in the past on the director's handling of > signals, and found sparse data.
