Note that once you have multiple outstanding transactions with the same TID/GID/method, the specific RMPP transaction will be sure to fail since ACKs will get matched to the wrong transaction. We are actually seeing these failures on big clusters when a diagnostic tool tries to get a list of all nodes from opensm: it seems to often retry the request MAD while the SA node gets round to responding to the first one. > It also seems that we're unlikely to hit any of these problems with the > current ib_sa interface. > > - Sean Possibly - we are seeing these when posting things all node port info request on top of umad. The problem appears on the opensm side. -- Michael S.
