aside from the mailman-users archives at


you might try a google search on "qrunner lock"

My best guess (a stab in the dark) is that at some point Mailman
died badly, leaving... the qrunner.lock file behind, blocking
qrunner from following its appointed rounds.

Since that's my guess, I'd have a look at the code for qrunner,
which shows me:

QRUNNER_LOCK_FILE = os.path.join(mm_cfg.LOCK_DIR, 'qrunner.lock')

So, in $MAILMAN_DIR/Mailman/, I have a look at Defaults.py, since I
am unlikely to have set up a modified version of LOCK_DIR...

LOCK_DIR        = os.path.join(VAR_PREFIX, 'locks')
VAR_PREFIX      = '/www/htdocs/orb/mailman/'

so, I look in  $MAILMAN_DIR/locks (in my case
/www/htdocs/orb/mailman/locks), and it's empty. If yours contains a
qrunner.lock file that is aging, then you might try deleting that
file and see what it buys you.

Best of luck,
