Hi,
Hello!
i use freeradiusd 1.7, rlm_perl with thread conf:
thread pool { start_servers = 100 max_servers = 1500 min_spare_servers = 1 max_spare_servers = 10 max_requests_per_server = 10 }
rlm_sql uses mysql.
All works fine, but sometime, at moment with high load:
Error: Discarding duplicate request from client nas_4:63429 - ID: 154 due to unfinished request 2176280
and radiusd like "frozen", take 99% of CPU time, and not response for client's request.
FreeBSD 6.3, Hardware is adequate - 2xXeon with 2 Gb Ram.
any ideas?
yep - your database cant keep up with either the authentication traffic, the accounting traffic or both. try using sql_log for the accounting - to take it out of 100% realtime for each incoming packet. also your config looks a bit wonky.
thread pool { start_servers = 100 max_servers = 1500 min_spare_servers = 1 max_spare_servers = 10 max_requests_per_server = 10 }
start servers = 100 max spare servers = 10 so the first thing it has to do it kill a load off(!) - set the spare to 100. how many SQL threads are you running? alan
