Version-Release number of selected component (if applicable):
kernel-2.4.20

How reproducible:
Sometimes

Steps to Reproduce:
1. Use the NAT script bellow
2. Perform some huge internet access

    

Actual Results:  The same errors and machine freezing

Additional info:

This machine is connected in an ADSL modem, performing a NAT to an internal 
network. This is the script that performs the NAT in the system initialization:

modprobe iptable_nat
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Today I got the same error, now running qmail_rspawn utility.

Comment 2 Need Real Name 2003-07-10 17:49:02 UTC
I solved the problem. I had a problem with my cooller... The processor was very 
hot :)

Thanks a lot
