Hi,

I have a very strange issue with Perdition. I have two Redhat Linux Vmware Vms behind a Cisco Ace load balancer. The load balancer is setup with a nated nat so that hosts on the same subnet can talk to each other. Recently we've had some incidents where it appears that Perdition is trying very hard to talk to itself resulting in a connection storm.

Perdition is querying an ldap system for the server to which to route the outgoing connection. This is perdition-1.19-rc5, Redhat Linux scout02.mail.cornell.edu 2.6.32-358.6.2.el6.x86_64 #1 SMP Tue May 14 15:48:21 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

Any clues would be greatly appreciated.
