I'm seeing some very strange behavior on one of our storage servers recently, and am wondering if anyone else has been experiencing similar issues. I think it may be related to InfiniBand somehow, but not sure. Unfortunately there are no error messages in the logs of any kind. But network traffic out of one or more interfaces just stops, or some traffic (ping e.g.) will work, but ssh/tcp won't.

Seen with both 2.6.32-431 and 2.6.32-358.23.2, and I think 2.6.32-220.23.1.
