<br>
From a DS point of view, you may use logconv.pl to get a rapid
summary of the received activity (DS access logs).<br>
You may take the same period of time on each server and compare
the results. It will give hints to know if the difference comes
from bind, connections, replication session, or ...<br>

<div><span class="261564008-01062015"><font face="Arial" size="2">We
don't have access to the _SRV_ records as the AD domain
controls that, so we had to hard code the main and failover
servers on the ipa_server line in /etc/sssd/sssd.conf, the
kdc line in /etc/krb5.conf, and the URI line in
/etc/openldap/ldap.conf. As such, it's reasonable to
suggest that our randomised script for
allocating primary/secondary on a client isn't as random as
we think.</font></span></div>

<div><span class="261564008-01062015"><font face="Arial" size="2">Might
it also be possible that due to the hard coding option we
had to take, our clients end up failing over to a certain
server, but then never failing back when the primary
returns? Under maintenance we generally patch and reboot
the odd numbered servers, followed by the even servers once
the odd servers are back.</font></span></div>
