To clarify some points: 1. the bounce mail is genuine. My logs show that a ~5MB mail was send to the list by the owner of the list, it was distributed to the members of the list, and caused some bounce mails by some recipients. The mail that caused the problem was normal non delivery notification with the characteristic that the complete original mail was included as message/rfc822.
2. I don't know if the size of the bounced mail has an impact on the number of duplications, but the size combined with the duplications resulted in the bounce process requesting using ~20 GB of ram 3. My logs indicate some cases with >2000 processed bounces that didn't crash the BounceRunner, most likely there was also a duplication, but the mail was smaller At the moment I try to create a striped down version that I can share that reproduces the problem -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1859011 Title: bounce mail processed multiple times -> oom crash of BounceRunner To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1859011/+subscriptions _______________________________________________ Mailman-coders mailing list [email protected] https://mail.python.org/mailman/listinfo/mailman-coders
