Are you able to identify anything that can trigger the crash? - Nothing found except the segafult I found, no load, no OOM, no IO, etc. The machine was really quiet at that time when crashed - most of the activity seems to be after the event, which is likely the sssd restart.
Is anything else crashing in a similar way on the same system? Random segmentation faults may indicate a memory corruption issue. - No only the SSSD Did the rpcmgr segfault happen on the same machine or on a different one, as the system hostname in the log snippet suggests? If it happened on a different machine, do you have any reason to think it's related to the sssd crash? - It's from different machine. I found this at just the second before `sssd` got killed. Could you please include a fuller version of the system logs? - Sure. ** Attachment added: "syslog.5" https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/1883614/+attachment/5385363/+files/syslog.5 ** Changed in: sssd (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883614 Title: sssd got killed due to segfault in ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/1883614/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
