Out Of Order TCP-Segments are not recognized:
a GIOP request is sent with frames f1 and f2 from the client, unfortunately the
frames arrive in the order f2, f1 at the server:
a.) when an out of order frame (f2) arrives it is erroneously recognized as
"previous segment lost",
b.) a following ACK on another before frame is recognized as DUP ACK
c.) when the first frame (f1) arrives it is recognized as "Retransmission".
d.) all further reuest from the client are treated this way.
a uuencoded trace fragment will be attached
