Thanks for filing this bug in Ubuntu. Do you know what is making this call every 5min? I couldn't locate a cronjob about it.
You seem to have other services also failing to start: -- Logs begin at Tue 2018-02-27 14:59:49 EET, end at Mon 2018-03-05 14:25:05 EET. -- Mar 05 14:19:03 hostname systemd: Failed to start AppArmor initialization. Mar 05 14:19:04 hostname systemd: Failed to start AppArmor initialization. Mar 05 14:19:07 hostname iscsid: iSCSI daemon with pid=1781 started!

Mar 05 14:19:12 hostname systemd: Failed to start Service for snap application canonical-livepatch.canonical-livepatchd. I will need a few more logs to properly diagnose this. Could you please attach the output of: - dmesg - cat /var/log/syslog - free -h Thanks ** Changed in: postfix (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1753470 Title: Postconf segfaults every 5 minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1753470/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
