  Hello all. I've been using UltraMonkey for a dual server setup. I have 3 servers behind a pair of ldirectord boxes all running CentOS 5.2. The connections that come in from the outside (go through ldirectord) are synchronized properly and when a failover happens, the connections remain open and running. 

  However, when a connection is started by the nodes behind the load balancers, and a failover occurs, the connections are dropped. I've managed to keep the connections running using conntrackd-tools, but I'm wondering if I setup something improperly with ldirectord / ultramonkey or if this is a limitation of UltraMonkey.

Ex:
  Works:
  outsidebox$ wget http://mycluster/bigfile.img
    ** wget runs, failover happens, connections are still running **

  Fails:
  lbnode1$ wget http://somehost/bigfile.img
    ** wget runs, failover happens, connections are dropped **


Thanks in advance!
