Hello.
Sorry for the delay in confirming the minimum load that would trigger
the RnR error; the holidays here were a significant interruption.

Our nodes with these HCAs are dual-socket, 4 Intel cores/socket.
Working with the users, it turns out we were unable to reproduce the
issue with anything less than 3 nodes and 17 processes total, with no
nodes oversubscribed. So two nodes were running with 8 processes each
and the third with 1 process.
It could be some sort of race condition or timing issue that could
theoretically be triggered for less than this, but we weren't able to
provoke it.

Just as a reminder, I responded to the firmware part of this earlier:
