I do not believe it to be the load-balancer. They log loss of contact
with the LDAP servers and drop them from the relay group shortly after
one of these events start; and when it gets cleaned up, they're added
back in. I also do not suspect network between the load balancers and
the LDAP servers.
During such an event, ps -efT will usually show slapd running at full
thread capacity. Comparing that to threads in cn=monitor is not
possible, as those ldap searches fail.
Open sockets does not substantially change until after the event
subsides. The servers will show 1200-2000 open sockets before an event,
and drop lower when it clears up -- to quickly scale back up to
pre-event levels.
The queues will show data being held until the socket(s) time out.
Thanks for the feedback!
