I have two BM38 servers that are the ICP parents for the network. Each
site has a local proxy, configured to use both of the ICP parents with
differing priorities. Both of the parents have Round Trip Time enabled.

Today, I updated the IP stack on one of the servers and rebooted it.
When the server went down, the call center started getting calls that
many users were getting 502 error in the browser, which tells me that
the proxies are not failing over to the other parent. Is this possible
to do?

Also, my rudimentary analysis shows that one of the BM servers is
handling much more of the load than the other. Is there any way to
better load balance the proxy requests to spread the load around?
