The box I'm seeing this on has a single inet interface "eth0,"
which is connected to LAN.
# ip addr add 172.27.0.1/16 brd + dev eth0 label eth0:1
$ nmap -sP -T Insane '172.27.*.*'
There are no live addresses from the 172.27.0.0/16 range on the LAN.
After about a minute into the ping sweep, nmap starts printing messages like:
Strange read error from 172.27.4.26: Transport endpoint is not connected
Strange read error from 172.27.4.27: Transport endpoint is not connected
Strange read error from 172.27.4.28: Transport endpoint is not connected
...
and dmesg reveals these errors:
Neighbour table overflow.
NET: 46 messages suppressed.
...
Then, trying to issue a simple "ping 172.27.5.5" results in:
connect: No buffer space available
I'm unable to reproduce the problem with a 2.4 kernel.

I've just verified this problem exists in 2.6.1-rc3 as well as 2.6.1-rc2-mm1.
