I'm not really sure what you need as a good backtrace, since I'm not a
programmer. I always thought that segfault lead to a program crashing. I
just don't know enough about gdb to know when there is enough information.
All I know is that when it crashes when running as a daemon, I get a
traceback that is useless in my e-mail (says no ptrace). When I run it under
gdb and get the segfault, when I type 'cont' it says that bacula-sd has
exited, and when I run it again, it doesn't complain that a process is
already running. In both cases, there is no process called bacula-sd running
on the system.
I updated/upgraded about 10 clients yesterday to using TLS, and I did not
get a crash from the SD. I will keep running it under the debugger in case
it crashes again, although, I'm not sure how useful it will be if I can not
operate gdb correctly to get you anything helpful. I have a feeling it's
some perfect storm of configuration that may be causing the issue. I've been
running Bacula for 6 years and never have had a problem like this. I'm just
trying to help the project be as robust as possible because we like it and
it has treated us so well in the past.
As a side note, I get a lot more connection timeouts and broken pipes when
using TLS, adding heartbeat interval helps, but it is not a silver bullet.
Most of the back-ups are succeeding with only a few here and there having
problems. Not using TLS and not having heartbeat interval, the back-ups
aways succeed. I'll keep working through things and see if I can come up
with anything.
Thank you for the time and the great project.

P.S. We are working on a support contract and will be talking with you in
about 24 hours with many others from our group who are also interested in
using Bacula.
