[expert] syslog stopped working?

[Bob Chin]

After about 4 days of uptime, klogd stopped working.  I use ipchains and
ip masquerading and noticed that /var/log/messages stoppped logging
denied packets and other info like kernel: ip_masq_ftp OUT: got PASV.
After I restarted syslog, it started logging again.  Anyone experienced
this before.  I have since updated the sysklogd package from
MandrakeCooker to see if the problem goes away.  Thanks.
