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.
