linux kernel: printk: 39476 messages suppressed.

I'm running Mandrake 10 Community as my school server. It works almost perfectly except that it can completely freeze the system every now and again. The error messages that concern me appear in the /var/log/messages file. Here is an extract.

Apr 5 09:46:59 linux kernel: printk: 39476 messages suppressed.
Apr 5 09:46:59 linux kernel: Neighbour table overflow.
Apr 5 09:47:04 linux kernel: printk: 38391 messages suppressed.
Apr 5 09:47:04 linux kernel: Neighbour table overflow.

This repeats itself over and over again.
What does this mean?
Is this causing the crash?
What can I do to stop this?

i think this should happen because you have your loopback interface down... you should ifup it automatically by adding the following lines to /etc/network/interfaces:
auto lo
iface lo inet loopback
then, ifup it with "ifup lo"

lisa service

I had also this problem on my system.

I detected eth0 was transmitting a huge amount of packets, even if disconnected.

Also the arp table was full of non-existing addresses.

I stopped the lisa service, and everything calmed down immediatly.

I did't dig in the configuration of this service, because i don't really need it by now, so I can't be more specific, sorry.

Hope this will help...

Shutting down Lisa did the trick. Thanks a million!!
I hope it also stops the odd system crash.
