Hi there,
I may be mistaken but... these are log message on the NAS aren't they?
If this is the case, I've experienced similar behavior with Cisco VoIP
routers (RADIUS Server DEAD and then... ALIVE). This happens if you
haven't properly enabled concurrency in FreeRADIUS - the CPU usage
stays low 0%-1%-2% but if the requests are many they are obviously
waiting each other... This happens when you have stared FreeRADIUS
with the -X key (I think it starts with a single thread then) or have
too low values for the thread pool parameters (and/or the *_clones
options of rlm_perl which are to be deprecated soon). If you configure
proper values according to the expected usage (concurrent requests),
then the request won't wait each other to finish while the CPU stays
unused and you'll avoid this annoying message in your logs. A sure
sing that something like that is going on is the Acct-Delay-Time
parameter with values greater than 0 - that is for accounting not sure
for auth etc. Anyways if the values of that parameter are high (they
are in seconds I think) then the requests are waiting too long and
hence the error messages.

Thanks in advance.
Have you checked the output of radiusd -X if there is a reason given
or any other hint?
