lost authlog

I tested load of freeradius.
And I got the following results.

OperationSystem FedoraCore4
freeradius:1.1.0

client
  [bunji at jason radius]$ radclient -d /usr/local/share/freeradius -f auth_1_man.txt -n 200 -p 200 192.168.0.205 auth test123 > auth.log 2>&1
  [bunji at jason radius]$ cat auth.log|grep Received|wc -l
  10000
  [bunji at jason radius]$ 

  [root at jason ~]# tcpdump -i eth0 -v > pckt_eth0.dat
  tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

  [root at jason ~]# cat pckt_eth0.dat|grep "Access Accept"|wc -l

server (6636 lost)
  [radius at lee log]$ cat radius.log|grep "Login OK"|wc -l
  3364
  [radius at lee log]$


When load is high, log seems to be lost.

How can this matter be settled ?

Best regards,
