-- this means corresponding process - `sssd_be --domain abba.xx.priv.yy` in this case - was blocked too long on 'something' (longer than 3*timeout - see `man sssd.conf`).
You need to figure out what this operation is. For this enable `debug_level = 9` in [$domain] section of sssd.conf and let this happen again.
Then take the timestamp of '... was terminated by own WATCHDOG' message from sssd.log and spot the last operation before this timestamp in sssd_$domain.log.
