(Could the crash happened because the same fd number is re-used after the RDMA channel was destroyed? Then when the fd has an event, it'll be delivered to rdma_cm_poll_handler() while the fd is not really the RDMA channel handle any more) Reviewed-by: Peter Xu <pet...@redhat.com> Regards, -- Peter Xu
