This helps a lot already. We do have multiple runners.

I was able to flush the queue today by moving long lasting *.bak out of the
way, and at the same time stopped Postfix to allow mailman to process its
queue. It took about half an hour to process 8000+ messages. If no manual
intervene, it may take a few hours.
You can address this by stopping Mailman, moving qfiles/out aside, starting

I think I've done that before. So moving back files into the queue in
batches, doesn't have to stop mailman?
The real operational question here is each time if we have to stop / start
mailman to move files, than for large volume queues, it would take a lot
of manual process. The procedure I have used is:
- stop mailman
- move queue files or .bak file aside
- start mailman
- move some files back, or .bak back into the queue
(note files are moved back while mailman is running)
Sounds right? thank you so much for your help!
