Is it always BounceRunner?

What if any are the bounce-events-ppppp.pck files in
/usr/local/cpanel/3rdparty/mailman/data/?

Are there extraneous qrunners running? (try "ps -fAw | grep Runner" to
see if there's more than one of each runner.)

What is in /usr/local/cpanel/3rdparty/mailman/locks/ (stale or otherwise).

Put

LIST_LOCK_DEBUGGING = On

in mm_cfg.py and restart Mailman to get additional debugging info in the
locks log.
