So, rds-stress -I 2 reliably kills a QP. -I is the super secret undocumented flag which builds rdma ops from vectors of memory instead of from one buffer.
The rds-stress -r side always sees a send complete with an error:
[ 6764.919515] RDS/IB: send completion on 10.3.7.17 had status 10, disconnecting and reconnecting
The RDMA additions were after my time. Before I go debugging this from first principles, can someone give a quick rundown of what we might be messing up in an RDMA op to kill a QP? Are there places in particular that I should check for the details of what went wrong?
