Hi, There were few cases where SSSD seems to stop working and required restart when the server's load average gets high ~ 80 on 24threads(processors) platform. Running 6.5 centos with 1.9.2-129 x86_64 On 6.5, sssd_nss.log shows the following: Thu Jul 31 20:28:38 2014) [sssd[nss]] [sss_dp_init] (0x0010): Failed to connect to monitor services.

Also the /var/log/messages: Jul 31 20:26:22 sssd[nss]: Shutting down Jul 31 20:26:22 ssd[be[LDAP]]: Shutting down Jul 31 20:26:24 sssd[be[LDAP]]: Starting up Jul 31 20:26:24 sssd[nss]: Starting up Jul 31 20:28:34 sssd[be[LDAP]]: Shutting down Jul 31 20:28:34 sssd[nss]: Shutting down Jul 31 20:28:38 sssd[nss]: Starting up Jul 31 20:28:38 sssd[be[LDAP]]: Starting up Jul 31 20:28:40 sssd[nss]: Starting up Jul 31 20:30:05 sssd[be[LDAP]]: Shutting down Jul 31 20:30:25 sssd[be[LDAP]]: Starting up Seems like restart @20:30:25 didnt properly restart sssd daemon? I believe 1.9.2-129 is the latest avail? enumerate is false, ldap_network_timeout is 5 and we have multiple ldap_uri settings where hosts are separated by "," Would appreciate if you can shed some light on this. Thanks.
