[openib-general] RDMA write with immediate

status 13 is "RNR retries exceeded."  This means that the remote side
did not have a receive ready to handle this work request.

What are you trying to do here?  The between RDMA write and RDMA write
with immediate operations is sending immediate data consumes a receive
request on the remote system and generates a completion with the
immediate data.  So you need to post a receive to handle RDMA write
with immediate but not regular RDMA write.

Did you modify your app to post the receive here?
