Hi,
i have similar issue in 8.1-RELEASE with re0 NIC.
suddenly it stops responding, but ifconfig down, ifconfig up solves the
problem.
i crontabed a minutely check, so check this, its a workaround, but here it
is:
#!/bin/csh -f
set ping = `/sbin/ping -c 2 -t 3 192.168.1.2 | /usr/bin/grep -v "PING" |
/usr/bin/grep -v "transmi" | /usr/bin/grep -v "statis" | /usr/bin/grep -v
"round" | /usr/bin/grep "64 bytes" | /usr/bin/wc -l | /usr/bin/awk '{print
$1;}'`
set reload = "0"
if ( $ping != "2" ) then
if ( $ping != "1" ) then
/sbin/ifconfig re0 down
sleep 1
/sbin/ifconfig re0 up
echo "re0 reloaded by cron job made by SAMI" >> /var/log/messages
set reload = "1"
endif
endif
