Hi! I'm usgin RedHat 6.0 w/ a custom 2.2.14 kernel and glibc-2.1.3.
The system has been working fine for a long time and recently I've
started noticing "neighbour table overflow" kernel messages in
/var/log/messages. Coincidentally, the Apache 1.3.12 server running on
the box is NOT accessible. It starts just fine and binds to both IPs
(it's a multi-homed machine) on port 80 fine, but when I try to connect
using "lynx" on the Machine itself, I get a "Cannot connect to host"
message and "lynx" terminates.

I'm guessing it's related to the "neighbour table overflow" messages but
I'm not sure. Any ideas as to what this message means?

My system is a Pentium II-400 MHz w/ 256 MB of RAM.

Any help would be greatly appreciated.

Thanks!

Peace.....

Tom

This happened to be once; I think that the kernel's arp cache is
overflowing.

I solved the problem by separating the two ethernets the two NICs
were connected to. I'm not sure how much that would help you,
though.

Do you have a loopback interface defined?
