just realized that it's probably not an instablity, but some process is killing sssd:
[root@wn113 sssd]# zcat sssd.log-20150804.gz (Mon Aug 3 20:30:55 2015) [sssd] [mt_svc_sigkill] (0x0010): [pleiades.uni-wuppertal.de][5957] is not responding to SIGTERM. Sending SIGKILL.

The config file looks normal to me: [domain/pleiades.uni-wuppertal.de] cache_credentials = True krb5_store_password_if_offline = True ipa_domain = pleiades.uni-wuppertal.de id_provider = ipa auth_provider = ipa access_provider = ipa ipa_hostname = wn113.pleiades.uni-wuppertal.de chpass_provider = ipa ipa_server = _srv_, ipa2.pleiades.uni-wuppertal.de, ipa.pleiades.uni-wuppertal.de ldap_tls_cacert = /etc/ipa/ca.crt [sssd] services = nss, sudo, pam, ssh config_file_version = 2 domains = pleiades.uni-wuppertal.de [nss] homedir_substring = /home [pam] [sudo] [autofs] [ssh] [pac] [ifp] sssd.conf (END) Anybody seen something like this already?
