Hello,

with the semester just beginning we find that our Radius services (using UDP) 
can't keep up. The servers themselves are pretty much idle. We're using 3 load 
balancers and AuthBy HASHBALANCE - connecting to 7 radius instances on 5 
different servers (RHEL 6). We've been running like this for a few years. At 
peak we're authenticating ~15 users a second but we're now seeing tons of these 
messages (128231 on Thursday) on the load balancers and lots of users can't 
connect:

AuthRADIUS : Could not find a working host to forward messages

We're having a hard time determining the bottleneck. Should we just add a whole 
bunch of new instances on these idle servers?
