Summary0017690: Flapping interface
Description6 Centos servers is used to run CAE simulations in a cluster and we have noticed recently that CAE jobs have been failing. Looking at dmesg logs of one server and I can see the networking interface flapping down, then up a a few seconds later. This happens randomly every 12 - 24 hours or so.

The 6 servers are connected to their own 10GbE switch.

I am a Windows admin and don't really have much experience with Linux which is why the configuration with these boxes haven't changed.

Can anyone suggest anything?

Thanks,

I suggest you try one of the support venues such as mailing list and forums rather than the bug tracker.
