Do you think this is OK? Did it try to terminate the unresponsive
sssd_be, or did it just try to start a new one and ran into a
conflict with the old?

Surely I can increase the log level for sssd. I wonder why
sssd_be doesn't write its own log file?

I highly appreciate your effort on providing compatibility with
sysv init and others, but do you know that ipa-client-install (4.0.5)
dies without systemd? I cannot tell for more recent ipa versions,
since they are not available for Debian 8.

Maybe it would help to improve the way how the monitor checks for un-
responsive threads instead? We have no indication that sssd_be had
any problem, except for sssd trying to start a new one. Since sssd
couldn't I would assume that the old sssd_be was still up and running
and that sssd was the buggy part.

Would you agree to that?
