The server side may be rejecting the connection request as a duplicate. The event.status may provide some additional insight. It should contain one of the enum ib_cm_rej_reason values given in ib_cm.h (assuming that you're using IB and not iWarp). If the status is 'IB_CM_REJ_STALE_CONN' (= 10), then retrying the connection with a new QP may succeed. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
