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 couple days. Version-Release number of selected component (if applicable): 2.6.25-0.40.rc1.git2.fc9 How reproducible: I don't know how to reproduce it. Steps to Reproduce: 1. 2. 3. Actual results: Data stops being transferred over a network interface. Expected results: Network interfaces should continue to work. Additional info: 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.
