Thanks Chuck.

I have been looking at those settings as well.

On this page:

Under "Sun implementation-specific properties", there are a couple 
settings which seem like they might be likely culprits: (default: -1) (default: -1)

The docs mention HTTP and FTP connections, but I wonder if it could 
apply to DNS connections as well? And... if the default timeout is 
"forever"... then maybe this could explain why it's not failing over?
