Wireshark shows that the TCP window of a connection is filled. This means the program does not read the data fast enough after requesting the data. If I revert that commit on the top of -next (20120518), everything works as expected. regards, -- js suse labs -- 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/
