modprobe -r ip_conntrack_ftp problem

modprobe -r ip_conntrack_ftp problem

[Deepak Seshadri]

Hello All,
Good day!

When I try to restart iptables by "servce iptables restart", the process 
hangs in the "Unloading modules" section.
ps -ef|grep modprobe shows that it is trying to remove ip_conntrack_ftp 
module.
The CPU has shot to 100% usage. I am not even able to kill the module. Could 
someone, please tell me what is happening here? What is the workaround?
It does not happen always.

OS: Fedora core 2
iptables v 1.2.11
kernel: 2.6.8.1

Any help will be appreciated.
Thank you,
Deepak

Funny you mention this today. I rebooted a box last night because
of this same problem. This ended a 287 day uptime.

This was on an old RH 7.2 with:
kernel-2.4.20-28.7
iptables-1.2.8-8.72.3

I never bothered to send an email to the list because I assumed it
was an old 2.4.20 issue.
