Then unfortunately I can only suggest to set a more verbose debug_level
(maybe coupled with a logrotate settings to avoid flooding your disk
with logs) and monitor sssd.

Typically, this happens when the machine SSSD is running on is very
busy, the sssd_be process is blocked writing some large result from
LDAP, the monitor process considers it stuck and kills it. However, we
/should/ restart and reconnect the subprocesses.
