That is something several people are experiencing and it is being looked into.
Any help in debugging would be appreciated, I guess, since the problem is
indeed hard to spot.
Check the mailing list archives of topic: "Version 1.1.1 stops responding".

You could use Nagios and its RADIUS module. That's what we do and it works
like a charm. You can even say sth like: if the probe failed twice, do a
stop/start of service and see if it helps; if not, send a notification.
