  That means the following has happened:

- the server proxied a request to a home server
- eventually, the server gives up, and uses Post-Proxy-Type Fail
- while it's running that, the home server replies.

  That's wrong... it means that the request isn't being processed
through a module, BUT the server core thinks that a thread is still
processing it.

  Hmm... please try the v2.x.x branch:

https://github.com/FreeRADIUS/freeradius-server/archive/v2.x.x.zip

  I've found one thing which makes me go "Huh?"

  Hopefully that should fix it.
