Problems with SIMH-emulated ethernet

Hello,
	Forgive me if this question has been asked multiple times before.
However,I've done some Internet searching and found nothing.
	Sometimes, when I start the system up, on the console I'll periodically get the message:
qe0: xmit logic died, resetting...
This doesn't seem to impact my system performance any, though I sometimes get it often.
I'm just curious as to the meaning of this message, and what can be done, if anything, to prevent it.
Thanks in advance,
Zack.
PS: This is being written on the emulated system with mutt and sendmail and vi.
