Okay, this is really bizarre. After awhile, Simultaneous-Use just stops working and lets people log on more than once. (I haven't figured out how long "awhile" is at the moment. Definitely overnight, possibly a couple of hours.) At that point, it seems to stop running checkrad -- at least, there's not the usual delay while checkrad checks if someone is logged on: authorization happens almost instantly.
Restarting the server makes it work again. Has anyone seen this before, or have any ideas where I might check for what's going on? K. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
