Hmmm ... I wonder if it could be stuck in an infinite loop? It's
probably just a horribly bad plan choice, but ...

If you can attach to the backend with gdb, try "bt", then "cont",
then wait a few seconds, then control-C and "bt" again. Repeat
five or ten times and see if there's any consistency to the traces.
You should be able to just "quit" and leave the backend running
afterwards.
