[SSSD-users] Weird SSSD shutdown

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 L. ------ "The antidote to apocalypticism is *apocalyptic civics*.
