Description doug.kratky 2000-02-09 14:20:30 EST
Everything works fine for a while after reboot.  After some amount of time
(less than a couple of hours), networking stops working.  Can't ping any
remote IP addresses by name or address.  Other systems on network (e.g.,
Solaris, NT., etc. are fine).

When problem happens, "netstat -in" output, ifconfig output, all looks
okay.  If I do "ifconfig eth0 down" and then "ifconfig eth0 up", then
networking starts working again.

Is this on a machine with an AMD processor? If so, it could be connected with
one of my systems with an AMD K6-2/350 processor that also locks up after a
couple of hours.

See my bug #6258. I have a number of machines locking up.  Thought it was the
NICS, replace em but it still happens.  I suspect SMP now and am running stock
2.2.12.  I have reports that ifconfig eth0 down up restored connectivity.

Sorry, it was bug #9258.

I have a similar problem on two identical machines on different
networks, both stock redhat 6.1 installs with p-III and 3c509c
cards.  They stop talking through the gateway but can talk to
machines on the local network.  If left alone they will start
talking outbound after a random amount of time (10-60 minutes or
so).  If I drop the default route and add it back they start talking
to the gateway.  I'm not sure if it's the kernel since I have
6.0 machines that I've upgraded to 2.2.12 and don't have that
