Re: [Mailman-Users] OutgoingRunner Failing
Hi all, I have the OutgoingRunner process failing quite regularly, and this has resulted in a build up of mail in the qfiles/out directory. How do I find out what is going on in this process for it to be failing like this? I experienced the same problem running Mailman 2.1.5 on a FreeBSD 4.6 box. I couldn't find anything telling in the logs. I upped the number of times that the qrunner would restart from 10 to 50. Still had the problem occur. Now I have a cron job restart mailman every 4 hours. Nothing backs up in the outgoing directory now and I haven't notice any residual problems from this change. This doesn't get to the source of the problem though. :( I figured it might be something with the content of the messages but with hundreds of lists running on 4 different servers it isn't something easily tracked down. Additionally no other mailman users complained about it until now.

Re: [Mailman-Users] OutgoingRunner Failing (fwd)
Oh, I forgot to mention. I'm not running multiple slices so Greenburg's patch doesn't apply.

David Richards wrote: Hi Brian, I have seen the same problem as you described in your post, I was running a shared installation via NFS. With OutgoingRunner's running on each box. Would you expect this to have the same results? While the idea of running MM on multiple machines in itself kind of makes my head hurt, I'm pretty sure that you're seeing a similar if not the same problem that I encountered. The logs you've posted look identical. From what I could tell from the code, if you are running more instance of OutgoingRunner (or any qrunner, for that matter), you *will* have regular crashes. This is because (assuming 4 slices, numbered 0 through 3) each slice should manage 1/4 of the queue hash space. However, as coded, slice 0 will grab files from the *entire* queue, not just the first quarter. This results in a race condition. The qrunner crash is a result of both slice 0 and another slice seeing a file in the last 3/4 of the hash space, and both beginning to process it -- one will finish and erase the file, the other slice will crash. Try making the following change: In mailman-2.1.5/Mailman/Queue/Switchboard.py, change line 167 from if not lower or (lower = long(digest, 16) upper): to if (lower == upper) or (lower = long(digest, 16) upper): This completely eliminated my problem. Brian.
