Version is FreeRadius 1.1.6 (only reason > we haven't upgraded is change control, it's due shortly) Set all of the thread information to the same numbers: start_servers = 32 max_servers = 32 min_spare_servers = 0 max_spare_servers = 32 That way threads won't be created, but they also won't be deleted. I suspect it's the deletion of threads that is causing the problem. i.e. delete/create/delete/create/.../panic ! - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
