Can you Red Hat guys reproduce this in you test environment? </blockquote> Most of my tests are on RHEV with RHEL 7.1, I have not seen a crash of DS.

In that case they probably received quite high load..... otherwise it's also should be extremely low. We don't use kerberos, do not join clients, just the ldap feature.....
