  You mentioned earlier that you have more than one thread, perhaps
like the httpd example, where it launches several threads waiting for
connection. You could reduce the number of IDLE threads (and perhaps a
small bit of memory) by launching threads after the NutTcpAccept, so
you have at most 1 IDLE thread, that you must have anyway to keep the
service available.
  Other than that, you could try to do lazy memory allocations. This
includes avoiding static memory allocations, since the compiler will
reserve that chunk at compile time, even when not passing thru that
portion of the code.

Kind Regards,
