    Thanks a bunch to Jason Santos, who pointed out that I should be using
    flowcontrol.
    netstat -k | grep overflow showed MANY overflow errors. I've set the switch
    up, and set the following in /etc/system:
    set ge:ge_adv_pauseTX=1
    set ge:ge_adv_pauseRX=1
    set ge:ge_adv_1000autoneg_cap=1

    Problem solved! :) Once again this list proves awesome

    Cheers
    Steven
