    I have seen similar with Postgres 8.0 database. Occasionally I'll see
    a bge0 timout + reset error logged, but many times I'll just see a
    "socket closed unexpectedly" type of message from postgres. So far,
    every 5 days or so, the machine freezes during heavy DB reporting over
    the net. I have a S2881 mobo, though, with 4GB.

    I had another identical machine which was reporting in the BIOS that
    the memory size changed during normal operations, which was very
    scary...
