The kernel message is printed with KERN_CRIT level. so modify your /etc/syslog.conf to log KERN_CRIT messages to /var/adm/kernel or some other file. Note that in that way you will potentially loose a lot of important messages...

If you want to fix this particular message then just modify your kernel (file net/ipv4/icmp.c line 683) to printk(KERN_INFO "%s sent an invalid ICMP error to...); Dont try this if you dont want to mess around with the kernel. balaji
