Also 4 rules in the raw table and 4 rules in the nat table for port redirection. I don''t see how the actual iptables rules could effect the kernel though.>> It''s really nothing special... routing is actually less >> complex than bridging IMHO. >> >> Is this perhaps a 2.6.16 kernel bug?

I have 31 nodes and 2 have rebooted with this error so far. It''s especially hurtful as I just upgraded all nodes to the changeset listed in the original message yesterday. I''ll give it a shot, but I have absolutely no idea which node will reboot next.> Ian > >> Thanks, >> Matt >> >> Ian Pratt wrote: >>> Please can you describe your networking setup.
