 ****************************************************************
 When a client disconnects an implicitly (static) secure
 connection, if the client generates a close-notify alert,
 the SSL server passes a notification to the TCP/IP
 stack server.  The TCP/IP stack server displays the
 AMPX036I assertion message because it does not expect this
 notification on a connection that is secured statically.
 
 PROBLEM CONCLUSION:
 In SSLVMAIN.C when a worker thread is handling a connection,
 if a close-notify alert is received from the connection partner,
 the worker thread always informed the TCP/IP stack server
 that we received a close-notify alert by calling doHSioctl().
 This APAR changes the worker thread logic so that doHSioctl()
 is only called for explicitly secured (dynamic) connections.
 For implicitly secured (static) connections, a worker thread
 will now cause the TCP connection to be ended.
