Summary
After an undetermined amount of download, eth0 just stop
receiving/transmitting bytes
Description:
After working perfectly for an undetermined time / volume of download,
eth0 just stop working (i.e. : it won'n receive/transmit anymore bytes).
I just can see the 'drop' field in /proc/net/dev increasing, all other
fields just remaining the same.
I tried to bring eth0 down and up again and it doesn't work.
Ad it happens only during intensive download (>100Ko/s) I suspected a
security mecanism could have seen it as an attack, but I couldn't figure
out what mecanism it could have been. Comparing /proc/sys/net both in
working and stopped situation with a
more $(find net/ -type f) >~/sys.net.ok
and a
more $(find net/ -type f) >~/sys.net.stopped
I found strictly no differences (i.e. the 'diff' command found no
differences)

Note : I have a problem with my NIC : it has its MAC address set to
00:00:00:00:00:00 by default and I have to force it to its real MAC
address specified in /etc/sysconfig/network-scripts/ifcfg-eth0.
I hope this report might be of any use for you (and for me ;-)
Thanx
