    The SO0001 is due to a PURGE of a task waiting for TASKASOC
    storage as part of a SOCK CREATE for an outbound socket.  The
    DFHSOLD ADD proc calls TaskAssociationManager.create_association
    but fails to detect if a TASKASOC block has been returned before
    trying to initialize it.

    ****************************************************************
    An EXEC CICS INVOKE WEBSERVICE command is issued to open an
    outbound HTTP socket connection. DFHWBCL calls DFHSOCK to CREATE
    the socket. DFHSOS13 is called to add a task association to the
    new socket object. The getmain for a TASKASOC object fails with
    a PURGED response because the CICS system is short on storage.
    DFHSOS13 fails to detect the error and tries to populate the
    task association object with a transaction number. This causes
    an ABEND0C4 which results in DFHSO0001 in module DFHSOS13
    followed by DFHSO0002 A severe error has occurred in module
    DFHSOCK.

Problem conclusion

  • The add method of DFHSOS13 has been changed so that a failure to
    getmain a TASKASOC block is detected and a PURGED response is
    returned.
