    SubjectStrange Network behaviour
    following Situation:

    4 Servers
    involved Hardware:
    - Motherboard: MSI MS-6728
    - Onboard Gigabit NetworkInterface: Intel 82562EZ (e1000)
    - 100 MBit NetworkInterface: D-Link DFE-530TX (via-rhine)

    Connected through a 1GB-Switch and a 100MBit-Switch. The second
    connects about 40 X-Terminals too.

    On all Servers is a SuSE Linux 9.0 professional installed; online
    updates every night. When they start up, everything is fine. After
    some hours when i want to do a tcpdump on one of the Interfaces i get:

    'tcpdump: socket: Address family not supported by protocol'

    ethereal doesn't find any interface.

    Sometimes some of the 100MBit-IFs didn't answer anymore. The only
    cure was to reboot. Neither rcnetwork restart nore unloading the
    network-module did help.

    This happend for a long time until there was a kernel patch from
    2.4.21-215 to 2.4.21-266. Since it is installed this error doesn't
    appear anymore.

    On my home-system with a sis900 NW-IF the same happend once. But
    there too is kernel 2.4.21-266 now.

    Does someone has have made the same experience or does someone has
    an idea what was the reason.

    Thanks for any ideas in advance
