Thanks. In the dump we can see that connections reusing ports always have their first SYN dropped and retransmissted three seconds later. I'm not sure whats causing this yet, do you have any firewall rules that affect loopback traffic? This filter (wireshark) shows one example of the problem in case someone else wants to have a look: (tcp.dstport == 1017 || tcp.srcport == 1017) && (tcp.flags == 0x02) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
