I had a programming problem. The server side of the program will execute ibv_ post_ send, return success. Every time I run for about an hour, there will always be a post after waiting long enough, I still haven’t received the post’s send_ complete event. I would like to ask, is there any good way to debug, or possible causes of this problem?
ibv_post_send and ibv_poll_cq in differents threads and not received IBV_EVENT_CQ_ERR or any other err events from CM and any async events from ibv_get_async_event。
