I just think it's not applicable to this situation. It is. You are saturating the port space, so no new POLLIN/accept events are sent (until some TIME_WAIT clears), so epoll_wait() returns nothing (or does not return, if INF timeo). Keeping only 1K (if this is what you meant with your *only* 1K) connections *alive*, does not mean the trail that does moving 1K connections leave, is free. If you ever played with things like httperf, you should know what I'm talking about. - Davide -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
