Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty for z/OS                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: An ABEND0C1/ABENDS0C1 occurs when       *
    *                      starting a Liberty server.              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    During Liberty server startup, the server process checks to see
    which version of the angel process it is using.  If the address
    space containing this Liberty server has been re-used, it may
    contain a name token pointing to heap storage that was used by a
    previous instance of a Liberty server.  This can occur when the
    initial pthread-creating task (IPT) of the new Liberty server
    uses the same TCB address as a previous Liberty server.  This is
    most likely to occur in a BPXAS address space or a batch
    initiator.  It cannot occur when the server is a started task.
    

Problem conclusion

  • Code was added to detect when an IPT TCB is re-used in an
    address space containing a Liberty server, to avoid the
    ABEND0C1/ABENDS0C1.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 18.0.0.2.  Please refer to the Recommended Updates page for
