CentOS - Apr 2008 - iptables: Unknown error 18446744073709551615 - no network connectivity from Xen VPS

Hi all

I'm getting this message on my CentOS 5.1 Xen VPS, after a yum update on 
a CentOS 5.1 x64 server. The main server runs CentOS 5.1 x86,  Linux 
2.6.18-53.1.13.el5xen #1 SMP Tue Feb 12 13:33:07 EST 2008 x86_64 x86_64 
x86_64 GNU/Linux

The VPS runs on

CentOS 5.1 x64 Linux  2.6.18-8.el5xen #1 SMP Thu Mar 15 19:56:43 EDT 
2007 x86_64 x86_64 x86_64 GNU/Linux

As such, I cannot ping the VPS from the main server, nor the main server 
from the VPS (I use xm console vm01 to enter the VPS). Any idea how I 
can fix this? It's on a production hosting server
