I suspect the error message he's seeing is unrelated to his performance
problem (not positive about that though).

As I mentioned to Brett in pvt email, it could also be the BounceRunner
that's hosing things.  By default, every 15 minutes it processes any
queued bounces, and if these were bounces to the site list, it will lock
every list on the system to register the bounce.  If he's getting tons
of bounces, or there's some bug that causes the BounceRunner to crash
(or the Python process to core dump???), he could be leaving stale locks
around that would wedge his lists.

There should be some evidence of this in the logs/bounce file, or in
stale locks in the lock directory.  He could also fiddle with the
REGISTER_BOUNCES_EVERY variable in BounceRunner.py to see if that
corresponds to the length of time until he's hosed.

If that turns out to be the case, then we'll need to investigate further
to find out what's giving his bounce runner grief.
