bareos FD - 24.0.5~pre41.f234ff58a Crash Dumped

[Markus Dubois]

after a long full backup run (16 TB), i got this on client side:
____

*** stack smashing detected ***: terminated

BAREOS interrupted by signal 6: IOT trap

bareos-fd, omvserver got signal 6 - IOT trap. Attempting traceback.

exepath=/usr/sbin/

Calling: /usr/sbin/btraceback /usr/sbin/bareos-fd 10 /var/lib/bareos

It looks like the traceback worked...

Dumping: /var/lib/bareos/omvserver.10.bactrace

___

unfortunately it´s a docker container in docker swarm, so i cannot access the trace file (at least i do not know how)

It's probably related to memory exhaust in the docker itself.

For the backtrace, if you can setup the mailing then the backtrace might be sent out of the docker when the crash occur.

Hi Markus,

See here: https://docs.bareos.org/Appendix/Debugging.html

> By default, btraceback uses bsmtp to send the traceback via email. Therefore it expects a local mail transfer daemon running. It send the traceback to root@localhost via localhost.

The last line of our btraceback script is:

$ cat /usr/sbin/btraceback
...
cat ${WD}/bareos.$2.traceback | \
/usr/sbin/bsmtp -h localhost -f root -s "Bareos ${DEBUGGER} traceback of ${PNAME}" root

Feel free to replace that mail address with one of your choice, or change the bsmtp to a different delivery method of your choosing.

It would be really helpful if we could get a copy of the traceback!

Kind Regards

Sebastian Sura
