The second item I noticed was that there was some odd traffic hitting it.
xxx.xxx.xxx.xxx = AlphaLinux box

128192 of these packets hit the machine in about 4 minutes. During that
time the buffer problem started. The machine's IP stack stoped working and
from a network pov. the machine was gone.
After the traffic stoped, network operations on the box no longer oprated
the same.
Any ideas of what happened here?
