this also sounds interesting, under extreme conditions, when, in our case, BT dropped around 30k users simultaneously during one maintenance window (SDH MUX software changes), we had to resort to forcibly killing and restarting our freeradius proxies every 5s in order to get users back online. it would handle requests for the first 2-3s after being started and then pegged at 100% cpu and served no further requests. any patches which touch the request load are of definite interest to us. I would appreciate it if you could forward them to me?

For my last major upgrade push, lasting some few months, I put in quite a bunch of patches for the system I am currently running -- iirc, thread requests and dying after the "thundering herd" was something I tried to deal with. Currently the last thing I attempted to address was preventing core dumps after mysql database becomes "locked". YMMV but you can have a look at it at http://www.jmaimon.com/freeradius specfically from the debian repository, grab the source package and look at the packages I am using today right now. Joe
