Running it under gdb without the debug options is better approach in that
case.

When it 'crashes' (though it sounds more like 'hangs' is a better word),
interrupt gdb with Ctrl-c to get back to the gdb shell window (as in step 8).

Martin and John, thank you for your replies.

I since yesterday afternoon, bacula-sd has been running under gdb using the instructions in the manual for my Bacula version, however I've still not seen the issue originally reported.

I agree with you both that by running it under a debugging process, it seems a delay is introduced which is suppressing the error in some way. Is my best bet just to leave bacula-sd running under gdb and hope that my full backups over the weekend may highlight the issue? Or is there another way I could debug this?

Thanks,

Joe
