Help withjk2 balancer problem

[chris humphrey]

We have a fairly complicated setup for jk2 that I believe should work, 
but after looking at the jk_workerr_lb source code, I am fairly certain 
this will not.

I am hoping someone has done something like this and has a solution.

We have a set of clusters, each cluster will process the same url's, but 
the sessions will only be replicated across to nodes on a cluster.  In 
the configuration, I am hoping to show 2 clusters, each cluster has 2 
ajp connections, and are put together using a cluster of lb's.

Everything seems to work at first, until failover to another cluster is 
required. The lb will attach to a  server, and failover inside that 
cluster.  But if both hosts in the cluster are down, the balancer never 
seems to failover to the second cluster.   There were also other 
problems encountered.....
