Red Hat Bugzilla – Bug 433594
Occasionally network interfaces stop working until restarted
Last modified: 2008-03-01 13:27:29 EST
Description of problem:
Occasionally network traffic will stop flowing over an interface. Using ifdown
followed by ifup clears up the problem. This may be happening to multiple
interfaces (but not loopback) at the same time, but I haven't checked carefully
(but will the next time I see it). I have seen it on both the motherboard
interface and a separate card. It seems to happen on the order of once every
Version-Release number of selected component (if applicable):
I don't know how to reproduce it.
Steps to Reproduce:
Data stops being transferred over a network interface.
Network interfaces should continue to work.
I am not sure in which kernel this started happening. I didn't see it when
running on f8.
I haven't seen this occur again since I reported it. My guess is that it was
probably fixed in a kernel update since then. If there are any fixes since then
that look like they might have covered this situation, then it is probably safe
to close this.
ok, feel free to reopen if it reoccurs.
