I would appreciate whether you could provide me with you test programs.
I will try them on my target. A bit more on the behavior we observe with
server_test.c: we found that the problem is in the "close connection
sequence"
(close(client); Line 128). One MBUF remains allocated because not all the
needed
"free functions" are called. In detail, close() does not call tcp_close().
The latter should call the free() for the tcp_template that we think remains
allocated.

The porting is distributed with 2.1 release version by goahead software.
