if I want to move quite a few *.bak aside (use timestamp as an indicator of how long they've been in that state), Is it necessary to stop the service, move files, then restart service? We have about 37,000 lists. Sometimes when I try to restart (/etc/init.d/mailman restart), OutgoingRunner won't go away, and had to be killed with -9.
This is really more involved than I can explain without a keyboard which I won't have before Tues eve, but there should be only one .bak file or one per slice if the runner is sliced. This is the message currently being processed. All others are ignored by the current runner (they will be "recovered" if the runner is restarted).
This helps a lot already. We do have multiple runners.
So I was wondering by moving files out of the queue without first stopping mailman, caused the OutgoingRunner to suffer.
Probably not, but it is possible. More likely, it couldn't be SIGTERMed because it was waiting for a SMTP response.
Make sense.
Note that part of the slowness at this point is due to the size of the out directory.
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
Mailman (which should recreate qfiles/out at the first message if not before) and then moving old entries back a few at a time.
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!
