 ERROR DESCRIPTION:
 Customer reports intermittent problems when an OSD device is
 started.  Message MSDTCOSD204E is reported when this problem
 occurs:
 
   DTCIPI023I TCP-IP initialization complete.
   ...
   DTCOSD204E ToOsd: Error 7D establishing CM-CM connection
              for device DEV@0600
   DTCOSD082E OSD shutting down:
   DTCPRI385I    Device DEV@0600:
 
 The '7D' error code cited here can vary, since this problem
 occurs from an incorrect mapping of the response buffer for the
 OSD device CM-CM connection (the error code reported is
 dependent upon the content of storage that is referenced).
 
 LOCAL FIX:
 This problem can usually be overcome by restarting the device
 in question, or if necessary, the TCP/IP server.
 
 PROBLEM SUMMARY:
 ****************************************************************
 * USERS AFFECTED: All z/VM TCP/IP users of OSD and HIPERS      *
 *                 devices                                      *

 * PROBLEM DESCRIPTION:                                         *
 ****************************************************************
 * RECOMMENDATION: APPLY PTF                                    *
 ****************************************************************
 The mapping of the response buffer for an OSD initialization
 command was incorrect.  An extra field was included in the
 mapping and therefore the code was looking beyond the end
 of the response buffer for a status field.  If the storage
 beyond the buffer was zero, everything looked ok.  If it was
 not, TCTOOSD would report the error with message DTCOSD204E.
 Note that the error code in the message varies depending
 on what is in storage.  Examples include 7D, 01, and 03.
 
 PROBLEM CONCLUSION:
 The mapping for the CmConnectSduType area was corrected.
