• 2 boxes with rl0, rl1, rl2, and dc0 each. Both are running 2.0 20090615.
    One is a Pentium and the other is a Pentium III.

    I enable CARP on dc0 at both boxes and set VIPs accordingly on LAN & WAN.
    A few minutes later and the Pentium does hangup and the Pentium III follows it after a few minutes.

    If CARP is disabled and VIPs too then no problem and each box is running fine for weeks in a standalone setup.
    I cannot figure anything in logs. Only what I can see is the following message at the console:

    "dc0: TX underrun: increasing TX threshold"
