>Release:        FreeBSD 3.*
>Organization:
sol.net Network Services - Solaria Public Access UNIX
>Environment:

ASUS P/E-P55T2P4D, 2xIntel P200 (or P133)
512MB RAM
3 x ASUS SC-200 PCI SCSI
1 x SMC 8434BDT dual 10/100 PCI Ethernet, 100mbps half duplex

Usually running Diablo

Ethernets plugged into one of:
3Com OfficeStack 10/100 (old or new)
Bay Networks 350F
Synoptics 20115(?)

>Description:

A network interface stops working.  The interface becomes un-pingable and
unresponsive.  The rest of the system remains functional.

This appears to happen every two to five days.  These motherboards and
CPU's were previously used under a slightly different configuration under
FreeBSD 2.1.7R, Matt Thomas's version of the de driver, with a single
P133 and {256|384}MB RAM, rest of configuration identical, with uptimes
in the two hundred day range.

This may be a hardware problem of some sort.  I experienced the _same_
problem with a much higher frequency under Solaris 2.6 x86 (SMP) on the 
same hardware, where it happened every six to eight hours.

I believe that I may have seen this same problem, once, on an ASUS
P2B-DS system as well.

See my next report for a possibly related bug.

>How-To-Repeat:

Unknown

>Fix:
	
Reset box, or

ifconfig <ifc> down; ifconfig <ifc> up

(I can usually log in via the other interface, which is on a private
network)

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?
