Hello Volker,
It looks like the segfault was in Bacula. This occurs if you reload the config
file -- there is a problem if there are jobs scheduled. It shows up when the
jobs run, and produces the seg fault. I'll fix this after version 1.38 is
released.
I don't think this seg fault is related to your hang problem which is surely a
mutex bug in Bacula. I am 99% this hang condition will be fixed in 1.37
where I have rewritten the locking code in the Director to use what I call
micro-locking rather than global chain locking. This incurs a bit more
overhead (more lock/unlocks), but avoids race conditions between multiple
threads when multiple mutexes is involved.
