I guess my solution is similar to j. Tole,
In my case, I had this error because my firewall guarddog doesn't keep its settings at boot, and was filtering that.
You can verify it with "iptables -L". To reload the rules at startup, I had to add in /etc/rc.d/rc.local:
if [ -x /etc/rc.firewall ]; then
/etc/rc.firewall
fi
