>Description:
	
	de0 goes OACTIVE after some time. I got no error in /var/log/messages
	nor in the console. The problem seems to happen when receiving incoming
	data at a high rate. The machine run httpd, ftpd, sendmail, ntpd and
	sshd. It happens every 2 or 3 days.

	The problem occurs with 2.5 and 2.5 + all patch and when the
	options NMBCLUSTERS is not set, set to 8192, or set to 16384

	I also tried with the patch for 2.6: 001_ifmedia.patch

	This is the output of ifconfig -a when the network is up:

	lo0: flags=8009<UP,LOOPBACK,MULTICAST>
		inet 127.0.0.1 netmask 0xff000000

	This is the output of ifconfig -a when the network is down:

	this is the output of /sbin/dmesg

>How-To-Repeat:
	
	I can reproduce the problem by putting a tape backup on the machine
	and backup another box on this machine using rmt. After about 10
	mins the network stop working and the OACTIVE flag is set.
>Fix:
	
	I don't know how to fix the problem.
