I have a setup such as: NAS > Freeradius Proxy > Freeradius Auth Periodically the NAS (different company and outside of my control) gets rebooted and when it starts up it sends thousands of simultaneous requests to the radius proxy, which in turn forwards them all to the appropriate freeradius auth server. The challenge is, the auth server can get overwhelmed and starts throwing some of these errors: Error: rlm_sql (sql): There are no DB handles to use! I'm curious if there's an elegant way on the freeradius proxy to rate limit the # of connections per second being thrown at the auth server. Ideally if the threshold is reached, requests above the threshold would be dropped (and not rejected). I've searched all the docs, the mailing list, and config files and haven't turned up a solution yet. Any help or advice is appreciated. - N
