I don't really deal with the NULL realm, so I'm not 100% sure of a certain configuration option's actions with said realm, but you might want to try setting 'wake_all_if_all_dead = yes' in the proxy.conf file. Assuming that wake_all_if_all_dead works with the NULL realm, this would at least help you test your hypothesis.
HTH,

I have a proxy server configured to proxy to the NULL realm.
This has worked fine until recently when it has started to silently drop RADIUS requests rather than forward them. The NAS does not recieve any response and so rejects users.
My hypothesis is that the RADIUS server it is proxying to becomes unresponsive temporarily, and so the proxy server marks it dead. Thus, when the next RADIUS requests comes along it has no server to proxy it to, thus it returns an error about the realm.
Would this hypothesis be consistent with the "No such realm NULL" error?
A possible flaw in this hypothesis is that the "dead time" is configured at ten minutes (dead_time = 600) yet the server continues to drop RADIUS packets beyond this time.
I would be interested in any ideas or suggestions to fix this.
many thanks, josh.
