Hi Andreas,
you attached the `.bactrace` file that the fd created. It would be very
helpful if you could also send us the `.traceback` file that was created
during the crash, as that file contains the stacktrace.
Without it we would have to guess were the problem occured.
As this problem occured on a restore, could you
1) check if this is reproducable, and if so,
2) send us the bootstrap record file of that restore job ?
If you give the restore command the option `bootstrap=<path>`, then
bareos will write the bsr file to that path and will not delete it.
Kind Regards
Sebastian Sura

Hi,
I have trouble restoring from tape. Jobs start as expected, but at
some point during the restore, the filedaemon is killed with signal 11.

Steps to reproduce:
1. Full backup to disk
2. Copy to tape via next pool
3. Restore from disk is ok
4. Restore from tape is not ok
What I tried without success so far:
- Deleted the jobs from tape and copied them again
The error occourred after the same amount of restored files
- Tried a different Tape
- Tried other fd versions. 22(debian), 23(suse) and 24(suse)
- Changed the blocksize to 512 in the sd
- Disabled compression and rerun everything
