Hi,
	I am using 2.6.16.13 kernel in smp configuration. Machine is working
as a gateway and frequent iptables commands are fired as users logged in and
logged out.

      I got following error in between

[root@manage /root]# iptables -nvx -L INPUT
ERROR: 7 not a valid target)
Aborted (core dumped)

So, I tried to flush INPUT and got following

[root@manage /root]# iptables -F INPUT iptables: Too many levels of symbolic links

following is a message I got in /var/log/messages

Aug 26 14:38:30 1219741710 kernel: iptables: loop hook 1 pos 0 00000022.

That kernel version has an iptables locking bug that might
lead to corruption. Latest 2.6.16 version has this fixed.
