mpd as a pppoe server in freebsd 6.2 crash

[Gloomy Group]

Hello all, I have setup mpd4.1 as pppoe server in FreeBSD 6.2, Intel P4 2.6GHz CPU and 512MB or RAM. I am facing two problem 1) When I give kill  -HUP   signal to mpd pid the server reboots.2) Another problem. Configured in /etc/newsyslog.conf for mpd log rotation  (/var/log/mpd.log                       664  7     900  *     JC        /var/run/mpd4.pid)But whenever log file tries to rotate the mpd process stop and I have to manually start the mpd.Any suggestion. Below is my configuration:mpd.conf---------------startup:        set web port 5006        set web ip 202.xx.xx.xxx        set web user test testpass        set web opendefault:        load pppoe0        load pppoe1        load pppoe2pppoe0:        new -i ng0 pppoe0 pppoe0        load pppoe_standard        set ipcp ranges 202.xx.xx.1/32 202.xx.xx.10/32pppoe1:        new -i ng1 pppoe1 pppoe1        load pppoe_standard        set ipcp ranges 202.xx.xx.1/32 202.xx.xx.11/32pppoe2:        new -i ng2 pppoe2 pppoe2        load pppoe_standard        set ipcp ranges 202.xx.xx.1/32 202.xx.xx.12/32pppoe_standard:        set auth disable internal        set auth enable radius-auth        set auth enable radius-acct        set auth acct-update 300        set radius timeout 10        set radius retries 3        set radius server 127.0.0.1 axzn 1645 1646        set bundle no multilink        set auth max-logins 1        set iface idle 7200        set iface disable on-demand        set iface disable proxy-arp        set iface enable tcpmssfix        set iface up-script /usr/local/etc/mpd4/linkup.sh        set iface down-script /usr/local/etc/mpd4/linkdown.sh        set iface mtu 1492        set link mtu 1492        set link no pap chap        set link enable chap        set link keep-alive 5 30        set ipcp no vjcomp        set ipcp dns 202.xx.xx.xx         set link max-redial -1        set link mtu 1492        set ccp disable mppc        set ccp disable mpp-compress        set ccp disable mpp-e40        set ccp disable mpp-e128        set ccp disable mpp-stateless        set pppoe iface rl0        set pppoe service "TEST"        set pppoe enable incoming        set pppoe disable originate-----------------------------------------mpd.linkspppoe0:        set link type pppoepppoe1:        set link type pppoepppoe2:        set link type pppoe
