I have a small issue with a RedHat 8.0 box. The ethernet connection intermittently terminates itself and then comes back up on its on. Output from ifconfig is below:
eth0 Link encap:Ethernet HWaddr *MAC Address*
inet addr:10.1.2.230 Bcast:10.1.2.255 Mask:255.255.0.0

route -n output below:

0.0.0.0 10.1.1.1 0.0.0.0 UG 1 0 0 eth0
Also when this occurs the other machines on the network can't ping this box(of course) and this box can't ping any other machine on the same network. This box can however ping the loopback and the ip address configured on the eth0 and eth0:1 interfaces.
service network restart has no effect but restarting the box will correct the error until it occurs again.
Also occasionally I see spurious 8259A interrupt: IRQ7 error message and have read posts on this and can't find anything that explains the error. All research done on this error message says that it is irrelevant as the machine continues to run.
Any help would be appreciated...
