Hi, I'm running this version of FR: # freeradius  -v freeradius: FreeRADIUS Version 2.1.10, for host i486-pc-linux-gnu, built on Nov 14 2010 at 20:41:03 OS is: # cat /etc/debian_version 6.0.5 # uname -ar Linux 2.6.32-5-686 #1 SMP Sun May 6 04:01:19 UTC 2012 i686 GNU/Linux it's a VMware VM with 4 vCpu and 1 GB RAM. Auth module is MySQL. FR is working but it takes 100% CPU. Other strange thing is that load does not rise more than 1 (it should be 4 or more). Any suggestion? This is my relevant config: max_request_time = 60 cleanup_delay = 5 max_requests = 102400   (I've 18 clients) thread pool {      start_servers = 32       max_servers = 256        min_spare_servers = 5         max_spare_servers = 20    max_requests_per_server = 0 } sql.conf sql {     num_sql_socks = 8     connect_failure_retry_delay = 60 } Thank you very much
