Thanks for the suggestions. I am very sure that this is not a load problem. When smtp/http port is unavailable with timeout, the other ports work fine. The log of both SMTP and HTTP daemon just freezed which means it's waiting for incoming connection. That's the weird point. The listen queue is full, but the daemon cannot get incoming connection by accept(2).
