CPU - FR1.0.5

Hello all, I've a problem with FR 1.0.5. I've installed it on an old server Pentium Intel 3 (no multi-threading) i've installed FR1.0.5 and radiusd take all CPU !! after a while, requests aren't more served.. kernel : Linux 2.6.9-1.667 #1 When i launch radiusd with -s option there is no problem.. Do you have an explication ? kernel is compiled with no multi-threading. I've an other radiusd on a pentium 4 with multi-threading and i have no problems on this server.. Thanks
