We are still seeing random intermittent stoppages of the SSSD
service.
Following Justin's advice I setup an stap script to catch what was killing sssd and
it's related processes.
It turns out sssd is killing itself. See stap output below. Would there be any reason for
this?

The SSSD debug logs should give some indication of what's happening
around the Nov 16 10:39:34 timeframe.
The primary SSSD service sends heartbeat pings to other SSSD services,
if there is no response from 3 pings then SSSD will attempt to send a
SIGTERM to the service.
Note:
https://fedorahosted.org/sssd/wiki/DevelTips#WhenIdebuganSSSDprocessinade...
The 'timeout' value in sssd.conf configures the time interval between
pings which defaults to 10 seconds but can be increased(it can be added
to each section of sssd.conf).
For example:
[sssd]
timeout = 60
[nss]
timeout = 60
[pam]
timeout = 60
[sudo]
timeout = 60
[domain/MYDOMAIN]
timeout = 60
Kind regards,
