Any other suggestions on where I should look to see why the servers are marking the upstream servers as Zombie?
The only log message is that it's marking the server zombie. Until it's marked zombie, it *might* be alive. The reason it's marked zombie is because the home server hasn't responded to the packet in the last "response_window" seconds. So... it's pretty simple. This *can* be caused by the home server selectively responding to packets. i.e. it responds to 1/2 of the packets, and ignores the rest. This could make the state "flip" back and forth between zombie && alive.
I failed to mention that the servers are marking only the accounting port on those servers as Zombie.
Yes. Any unique combination of (ip, port) is treated as a unique home server.
Please let me know if you want the 9MB debug or if you have recommendations for making a smaller debug file.
Nope. Look at the statistics using "radmin". You can look at individual home servers, and stats for received / sent packets. You might need to install the git "v2.1.x" branch for accounting stats, though. Alan DeKok.
