>Release:        FreeBSD 2.2.1-RELEASE i386
>Environment:
Server:
	CPU:			P5 166MHz
	Memory:			64MB DRAM
	Ethernet Card:		Intel EtherExpress 10/100B
	IDE Hard Drive:		Western Digital 2.1Gb

	This ethernet card has 68 aliases bound to it.

>Description:

	After running for anywhere from 12 hours to 2 days, the ethernet
card becomes unresponsive to any packets. The server continues to operate
though attempting to send or receive any packets fails. Netstat -nr shows
default route as well as the aliases. Netstat -na shows usually an address
bound to port 80 of one of the virtual webservers with a state of LAST_ACK.
Rebooting the machine returns all network functions to a normal state.

>How-To-Repeat:

	Probably sufficient to use an fxp device with multiple aliases
bound to the controller. This seems to exist now on two seperate machines.
The second machine ran without a single problem until I bound a couple of 
aliases. The symtoms are identical to the first server.

>Fix:
	
	Disabling aliases causes the problems to go away.
