Hi all,
RH7.2, kernel 2.4.18, iptables 1.2.5, 128Mb, uniprocessor box.

I'm getting some garbled entries in /var/log/messages :

The only LOG entry in my ruleset is:
#prohibit and log all other inbound traffic
iptables -A FORWARD -i eth1 -o eth0 -j LOG --log-prefix "FIREWALL: "
memory: (output of 'free')
# free
total used free shared buffers cached
Mem: 127084 119892 7192 0 6304 61532

Swap: 2097136 3412 2093724
Any ideas here?
Cheers,
Terry.
