FreeRadius 1.1.1 and run-away CPU

[Aaron Burruss]

Hi all.

 

I'm running freeraduius 1.1.1 on a FreeBSD 5.4 server.  I'm using the
mysql module (mysql 4.0.24), and everything seems to be working fine...
but at random times, the CPU becomes pegged by the radiusd process, and
it will stop accepting requests from my clients.  This does not (seem
to) occur when I run in debug (-X), but I obviously don't want to run it
in that mode for the long term.  I've looked around, and can't seem to
find anything that might be causing this to happen.  

 

last pid:  3745;  load averages:  0.51,  0.26,  0.53
up 0+18:46:06  09:29:34

41 processes:  2 running, 39 sleeping

CPU states: 46.7% user,  0.0% nice, 52.9% system,  0.4% interrupt,  0.0%
idle

Mem: 41M Active, 315M Inact, 105M Wired, 12K Cache, 111M Buf, 535M Free

Swap: 1024M Total, 1024M Free

This is a 2.8GHz box with 1GB ram.  Restarting the daemon sometimes
helps, for a while, then high CPU again.  Sometimes it spikes up
immediately.  Reboot has not helped.

 

Thoughts?
