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

    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?
