SSSD and Cassandra

[Marc Hoppins <ma...@eset.com>]

Hi all,

If SSSD stops responding to requests/listening, is this going to cause the Cassandra service to shut down?  I didn't see anything to indicate such behaviour in the config, only for disk issues.

I had two hosts where SSSD was not accepting logins and, after restarting that service and login, I noticed that the Cassandra service was also stopped.

Thanks

M

If multiple things are dying under load, you'll want to check "dmesg" and
see if the oom-killer is getting triggered.  Something like "atop" can be
good for figuring out what was using all of the memory when it was
triggered if the kernel logs don't have enough info.

Update: It may be that the load on these hosts is causing problems for SSSD not the other way around.  In any case, it seems that both services are off at the same time.
