I remember to have posted (maybe just privately) patches to catch 
Net::DNS problems in the past to avoid radiusd to keel over and 
gracefully handle them.   I lost track if they ever made it in.

I also used to have patches to get multi-NAPTR pointer support (try them 
in sequence until success and only then fall back to Route), as well as 
multiple Route entries back then in order to try different orders for 
fallbacks on different servers, etc.  (as you’d kind of know from 
other config parts).


In case any of this stuff would be interesting or help, I could go and 
see if I can find them again.
