(RADIATOR) Radiator crashes without trace

[Dave Kitabjian]

I think you said you're running at debug level 3? Try 4.

We had a situation a few years ago where garbled usernames were coming in and messing things up, causing processes to die (in our case it was the LDAP process that died, but it could just have conceivably been radiusd). And since the NAS didn't get a reply from the Radiator server, it "failed over" to the other Radiator server and "killed" that one, too.

So the fact that both are dying suggests to me that you probably have them in a failover scenario and there is some type of rogue RADIUS request that's coming in and taking them both out, one at a time. Trace 4 should help track down the rogue request and its contents...
