Possibly my invocation is wrong.
On Linux, use `strace -o strace.log -ff` to trace child processes as they are forked, and save output from them into `strace.log.$pid` files (makes it easier to analyze those traces) > I did also just notice in Bacula's jobs-run list that it thinks dbcheck > terminated with a fatal error.

Are you sure your server is not running out of memory and OOM killer not zapping your bacula invocations? (this should leave traces in /var/log/syslog or /var/log/messages or should be visible with journalctl command, depends on your distribution).
