OPT_KEEPALIVE Broken in RTCS 4.2?  Causing idle connection to RST in RTSC 4.2, but not 4.1

Greetings!

 

When I recently updated to RTCS 4.2.0.0 (and RTCS 4.2.0.1).  I have the OPT_KEEPALIVE property enabled on one of my "control" sockets that I am using for a home brew FTP server.

 

In RTCS 4.1, no issues, seems to work as intended.

 

In RTCS 4.2, when the control socket connection sits idle for a few minutes the server side (MQX/RTCS) the first KEEPALIVE sent ends up resetting the socket connection.  KEEPALIVE should not do this unless the remote side is gone.   Two keep alive probes from RTCS (ID=80 and 81), one keepalive response from the host , then RTCS resets the connection.

 

 

Any clues?!?!
