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.

Not observed here, including on ~160 systems with IB. But then we have no systems running -431 yet, few running -358.23.2, and none running kernels as old as -220.x.y. Most are on -358.x.y.

Thought it might still be a useful data point.
