After changing a client from using DHCP to using a static IP
address using netcfg I had severe errors during the reboot
concerning neighbourhood table overflow errors. Traced it
down to being a badly configured loopback device. The file
/etc/sysconfig/network-scripts/ifcfg-lo was found to be
truncated. It looked like this:
whereas it should look like this:
It appears that netcfg caused this file corruption.
I don't see how netcfg could have done that. If you can reproduce
it, I'd like to see the steps you took to do it so that I can make
an attempt to debug it here. Thanks.
Anyone who can reproduce this bug, please reopen this bug report
with an explanation of how you did it. Thanks!
