Public bug reported: After upgrading my mailserver to 16.04 I noticed that LDA delivery from Postfix->Dovecot->my IMAP mailbox was intermittently failing. The logs showed
"dovecot: lda(daniel): Panic: epoll_ctl(del, 10) failed: Bad file descriptor" A Google search led me to a Dovecot mailing list bug report[0] from March, and the subsequent reply[1] that led to a patch[2] from the maintainers to lib-sieve that addresses the bug at fault. Applying the patch commit[2] to my local Dovecot has fixed the panics and mail delivery is once again reliable. Thanks so much! Let me know if I can provide any other useful information. -cpu [0]: http://www.dovecot.org/list/dovecot/2016-March/103668.html [1]: http://www.dovecot.org/list/dovecot/2016-March/103694.html [2]: https://github.com/dovecot/pigeonhole/commit/a95b0579b89c13fb3ee5700e76cbe6a4a3e898e0 System information: Distributor ID: Ubuntu Description: Ubuntu 16.04.1 LTS Release: 16.04 Codename: xenial doveconf | head -n 2 # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) dovecot-core: 1:2.2.22-1ubuntu2.1 dovecot-imapd: 1:2.2.22-1ubuntu2.1 dovecot-lmtpd: 1:2.2.22-1ubuntu2.1 dovecot-sieve: 1:2.2.22-1ubuntu2.1 ** Affects: dovecot (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1635977 Title: Dovecot LDA w/ Sieve panics on deliver - bad file descriptor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1635977/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
