I would try running it in foreground with full debug mode turned on.
Since the process should be long-running, you'll probably want to run
it in a screen session.
Something like this should work:
$ bacula-dir -f -d 10 -v 2>&1 | tee /path/to/a/log/file
I'm not sure about the exact value to use with -d, some experimentation
may be required.
More hardcore options would be running it under strace or gdb.
But strace wouldn't show you a problem with memory allocation for
instance and gdb requires presence of debug symbols to provide for
useful post-mortem analysis.
