Hello!

This has happened twice to me already within a month of uptime...

The machine is 486DX66 running -stable circa March 1998. It has
two net interfaces -- de0 and ep0 (ISA bus, of course). de0 connects
it to the world through a cable modem and ep0 connects it to the
local net.

The problem is, the ep interface locks up sometimes. After heavy
network activity, I might add (last time it was shortly after
running a cvsup on one of the machines on local net, updating the
-stable tree on the firewall machine over NFS). There is no NATD
running, just the user-space socks5.

The symptoms are:

	* pinging local net machines from the gateway machine says:
		"No buffer space available"
	* pinging the gateway machine from local net machines says:
		"Host is down"
	* local net machines continue to ping each other just fine
	* all lights on the hub are fine
	* the other (de0) interface is functional, machine is
	  accessible from the Internet, continues to receive mail,
	  etc.

To heal the situation I had to (no rebooting, no):

	ifconfig ep0 down
	ifconfig ep0 up

Any ideas? Thanks!

	-mi
