One note after implementing EAPBALANCE.  I am getting this in the logs with a 
specific user at the moment.

May 17 07:52:09 riptide-2.vm.its.uwo.pri /usr/bin/radiusd[23274]: 
ProxyAlgorithm HASHBALANCE declines to break up an EAP stream after failover 
from 129.100.160.133:1645:1646 to 129.100.160.144:1645:1646

Here is the config snippet I have included.

<AuthBy EAPBALANCE>
        Log errorLogger
        Log western_syslog
        Identifier IVEY
        Retries 3
        RetryTimeout 5
        FailureBackoffTime 20 
        AuthPort 1645
        AcctPort 1646
        Secret xxxxxxxxx
        LocalAddress xxxxxx
 
        <Host 129.100.160.144>          
        </Host>
 
        <Host 129.100.160.97>
        </Host>
 
        <Host 129.100.160.133>
        </Host>
   
</AuthBy>

My interpretation of these messages is that the server the EAPBALANCE is trying 
to send the authentication packets to does not respond in the appropriate 
amount of time, the EAPBALANCE Hash does not want to break the authentication 
stream, but never times out long enough to move to another server?
Any input would be helpful.  My thought is to lower the values for Retries etc.
