answered.  Several times when I have left A/UX running unattended
overnight (I usually run my MacII with MacOS during the day) I have
come in to see the following error messages:

	ae0:overflow NIC reset failed
	ae6_intr:Receive overflow warning
	ku_fastsend: if_output failed: error=70, sendpck=0, am=0

Has anyone else seen this?  Any idea what is causing it?  I am still
awaiting an upgrade to my (older) Ethertalk board.  Could it be the
source of the problem?
=====================================================================
I used to have the same problem with my machine. Some time ago some
one posted a good suggestion that seemed to have cured the overflow 
problem. Try 
		kconfig -n /unix
		NMBUFS=800
		^d
		sync
		sync
		reboot
This will allocate 300 more buffers for networking, the default is 500.
you can read the manpages on kconfig to get the details on NMBUFS.

	Best of luck
