Over time, I’ve been having seemingly random sssd quits that I’ve not been able to figure out. Today, I finally traced it to fluctuations on my Infiniband fabric:

These messages should just tell sssd to reset its online/offline status. It's possible we have a bug there, but this code should be pretty stable, there were no changes there recently. Maybe the services don't handle the resetOffline signal well, but that's just my speculation.
There's no way to disable the netlink integration except for build changes.
Today, we merged the patch for disablink netlink integration. https://git.fedorahosted.org/cgit/sssd.git/commit/?id=7c475c3a02329f477f6245... https://fedorahosted.org/sssd/ticket/2860
It will be part of sssd 1.14.1 which should be released in few days.
