IPTables doesn't restart

[Nathaniel Hall <halln@xxxxxxx>]

I am running an RHAS3 firewall with IPTables.  When I restart IPTables, 
I get kicked out of my SSH session and everybody around campus gets 
kicked out of telnet.  Once I have been kicked out, I cannot re-login 
via SSH.

When I get to the local console of the firewall, I am able to login with 
no prob and restart IPTables with all succeeds and everything goes back 
to normal.  I took a look at /var/log/messages and here is what I get:

   /Start of IPTables restart/
   Dec  7 14:58:44 cs-fw iptables:  succeeded
   Dec  7 14:58:44 cs-fw last message repeated 2 times

buckets, 65528 max) - 304 bytes per conntrack
   Dec  7 15:03:32 cs-fw iptables:  succeeded
   Dec  7 15:03:32 cs-fw iptables:  succeeded
   /End of second IPTables restart/

Any ideas?
