Error description

  • ABENDS0C4 occurs in a nodeagent when using local communications
    from a nodeagent to an application server that is being stopped.
    The callback stack that generated for the NA TCB that had the
    0C4 looked like this:
    CF_Local_Connection::clientSend(LocalComm_IOV_Header*,int,in

    * PROBLEM DESCRIPTION: ABEND0C4/ABENDS0C4 occurs in a          *

    *                      occurs because the private storage of   *

    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When a application server is being stopped there is a timing
    window in which the private storage for the PC routine has
    been removed but the PC entry in the LXLIST has not. This can
    result in an Abend S0C4 if the nodeagent attempts to use local
    communucations to access the application server as it is
    stopping.
    

Problem conclusion

  • During controller task level termination processing an LXFRE
    was added to remove the PC routine from the LXLIST to prevent
    access to the PC routine, whose private storage has been
    removed, during controller termination.
