SubjectRe: [2.2.9] performance problem on 100MBit network
   Date: 	Sat, 22 May 1999 16:08:30 +0200
From: Jochen Heuer <>

Sometimes I get ping times of up to 20 seconds(!) while normaly
ping times are ~0.3ms. If this happens I have to reboot either my
server or my client.

What can I do to debug this if it happens again?

Let me guess, you see this behavior on systems where DHCP is running
in some way? And it happens about when a client rebinds, and the
machine in question is going ARP crazy if you watch it on the network
with tcpdump?

Did I guess right?
