The usual reason for a RST being sent in this situation is if there is still 
data queued on the socket for the client application to read.  I would have 
thought the shutdown(RDWR) would have dealt with that.  Just to make sure, you 
could try explicitly trying to read from the socket just before you close it.

If the client application closes the socket but the process doesn't exit, is 
the RST still sent?
