OK, so the fd is getting a segmentation violation signal.  It is trying to
email a backtrace to localhost, but that is failing because there is no smtp
service running.


You could also try running the fd under gdb and then run the gdb commands:

bt
thread apply all bt
info all
x/i $pc
x/64i $pc-0x30


Ok, here's what I did:

on heRPI02:

ps aux |grep bacula-fd  -> PID 540

gdb

 - attach 540

and pressing ENTER until there was a prompt again.

then keypunching your commands:

> bt
> thread apply all bt
> info all
> x/i $pc
> x/64i $pc-0x30

then started the job via bconsole 'run accurate=yes'

The error "gdb cannot find "../sysdeps/unix/syscall-template.S"" seems to be benign acc. to https://sourceware.org/ml/gdb/2016-01/msg00016.html

The error "Backtrace stopped: previous frame identical to this frame (corrupt stack?)" seems to be more serious.

But what really wonders me is that there does not seem to be any output
after I started the job via bconsole.

I guess gdb is keeping the bacula-fd process from segfaulting, because
it is still in the process list. No idea what the state "tsl" is. It's either not stated in man ps or I've overlooked it.

root 540 0.0 0.4 19508 4900 ? tsl 11:50 0:00 /usr/sbin/bacula-fd -f -c /etc/bacula/bacula-fd.conf socrates 1848 0.0 0.0 6320 544 pts/1 S+ 16:32 0:00 grep --color=auto bacula


Now bconsole says as for status dir:

Running Jobs:

I'm sorry but I guess this is not very helpful :-(



best regards,

Thorsten
