Any way to solve "watchdog timeout" on network-IF?

I'm using FreeBSD/i386 6-stable on HP DL360G5 server,
and getting "Watchdog timeout" & "link state changed to DOWN/UP"
messages shown below.
bce0: /usr/src/sys/dev/bce/if_bce.c(5000): Watchdog timeout occurred, resetting!
bce0: link state changed to DOWN
bce0: link state changed to UP
[System I'm using:]

Give UDP generating load (ports/net/rude was used).
[FreeBSD]-(bce)--- 100BaseTX-switch ---(em)[FreeBSD]
packet genarator --------------> packet receiver
70Mbps UDP, 1400Byte packet * 6000pps.
Then, the above "Watchdog timeout" message occurs _SOMETIMES_.
Maybe once a week, sometimes 10times/day.
I've tested with 3 hardware(all HP DL3x0 server with BCM5708 chip),
and all of them seems to suffer with this.
I've suspected new bce-NIC, and tried with bge cards
(also with FreeBSD 6-stable).
However, similar message also happens with bge(other network IFs also).
Next, I've tried with other cable, other ether-switch, but
they still seems to happen _sometimes_.
Are these "Watchdog timeout" events common and happening everywhere else?
Or am I doing something wrong?
Searching the -stable archive, there seems some other people
suffering with this:
2006.11.29 [Re: Dell PE 1950 bce NICs revisited]
2006.12.14 [em watchdog timeout]
