Actually, that is different behavior. This bug is handling an issue where the
SSL record layer is fragmenting SSL data into multiple SSL records (which in
turn wil be segmented by TCP).

TCP segments that are out-of-order are a general problem with tcp-reassembly.
If they are caused by duplicate packets (as in your trace) you might want to
filter out the duplicates with "editcap -d"

Duplicate ACK's and lost ACK's should not be a problem though...

Then you might want to open a new bug for the problem with TCP reassembly when
packets are out-of-order.

Cheers,


Sake
