>Description:
Hi
1.I have installed PPPoE server with config: 

default:
   set log Warning
pppoe-in:
   set mtu 1492
   set mru 1492
   allow mode direct
   enable lqr
   set lqrperiod 5
   set timeout 6000
   disable acfcomp protocomp
   deny acfcomp
   enable chap
   set speed sync
   accept dns   
   set dns 192.168.1.1
   set server +3000 password
   set radius /etc/radius.conf
   set rad_service_type 11
   set rad_alive 60

2.I have one ethernet card "em0"

3.My sysctl.conf is :
# $FreeBSD: src/etc/sysctl.conf,v 1.8 2003/03/13 18:43:50 mux Exp $
#
#  This file is read when going to multi-user and its contents piped thru
#  ``sysctl'' to adjust kernel values.  ``man 5 sysctl.conf'' for details.
#
# Uncomment this to prevent users from seeing information about processes that
# are being run under another UID.
#security.bsd.see_other_uids=0
net.link.ether.inet.proxyall=1
net.link.ether.inet.max_age=300
kern.ipc.somaxconn=1024
####MASK POD WINDOWS###########
net.inet.ip.ttl=128
####LOG########################
net.inet.ip.fw.verbose_limit=1000

4.The pppoed run with parametr:
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0

Sometimes ,this appear not offten when i press ps aux i see 
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0

and my pppoed not working properly

When i press the command arp -ad the problems are disappear.How can i fix this problem. If i press command ps aux i see
/usr/libexec/pppoed -P /var/run/pppoed.pid -l pppoe-in -c 10 -p * em0
only one demon, and etherything is fine. The pppoe client is adsl modems like Zyxel,Dlink.
