Hi, I'm using RDMA CM to manage connections above IB layer.
After connection is established, IB async events are polled using the file descriptor found in the associated connection id returned by RDMA CM layer: ibv_context->async_fd and proceed using ibv_get_async_event(). But the only event I caught and handle is IBV_EVENT_COMM_EST because it happen sometimes under high load (in this case, rdma_notify() is used to send the event back to RDMA CM layer). RDMA CM event are monitored using an event channel created by rdma_create_event_channel(), polled using file descriptor rdma_event_channel->fd and later processed by rdma_get_cm_event() on event. I'm suspecting there's some race between RDMA event channel ( / rdma_get_cm_event()) and my IB async event monitoring. So here's my question: should I monitor async events using ibv_get_async_event() or is it fully managed by the RDMA CM layer ?
