Last night sssd shutdown on one of my servers.

I had updated the IPA server earlier in the day - but only patches to 4.5.0, nothing major.

The error I saw this AM was:


(Wed Nov  1 17:08:22 2017) [sssd[be[unix.domain.com]]] [orderly_shutdown] (0x0010): SIGTERM: killing
children
(Wed Nov  1 17:08:50 2017) [sssd[be[unix.domain.com]]] [sysdb_domain_cache_connect] (0x0010): DB version too old [0.18], expected [0.19] for domain unix.domain.com!
(Wed Nov  1 17:08:50 2017) [sssd[be[unix.domain.com]]] [be_process_init] (0x0010): Unable to initialize domain
(Wed Nov  1 17:08:50 2017) [sssd[be[unix.domain.com]]] [main] (0x0010): Could not initialize backend [1432158275]


None of the other servers that use sssd/ipa were affected?

Would appreciate any insight into what happened.

I guess the questions I'd ask are:
 - error is obv - db version. Is it that obv?
 - that said, why only one server and not all of them?
 - Should I expect the others to fail soon?
 - why now? I've updated ipa and sssd numerous times without seeing this error that I know of.

Cheers
