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.
