HI Alan This is 3.0.15 I can upgrade the server to .16 that's not a problem. Also happy to compile a debug version and run here (the server is production with real requests - but can happily run in debug mode with the debug symbols running. Also happy to share the log file (ideally privately since it has some details of the realms - and client data) in it. Initial email was more a generic comment - but will happily run the debug as needed Richard

We have a realm that we are trying to proxy. For auth it works fine... BUT for accounting it fails. Running radiusd -X when we get an accounting packet we get the following:

What version of the server are you using?

See doc/bugs, which describes how to get more information.

Auth requests that are proxied to the same server. The home server is another freeradius server.

After some digging I have found the cause - which MAY be of interest .... in proxy.conf one of the realms was duplicated

Hmm... that should be forbidden. I'll check.

...

With a single instance all is good - but occidentally duplicate and this is reproducible here.

This is not high prority in any way and was triggered by a config issue - BUT I thought this might be interesting.

If you need any extra information let me know - I am more than happy to help
