Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of the z/OS NFS client who         *
    *                 encounter the User ABEND of U2049 in         *
    *                 GFSCRTHD module.                             *
    ****************************************************************
    * PROBLEM DESCRIPTION: The User ABEND is triggered because of  *
    *                      the insufficient serialization when the *
    *                      z/OS NFS client schedules the 1st       *
    *                      AIO_RECV upon handling AIO_CONNECT      *
    *                      completion.                             *
    ****************************************************************
    Obtain the proper serialization.
    

Problem conclusion

  • Obtain the necessary serialization since the first scheduled
    AIO_RECV can immediately fail (due to AT-TLS handshake failure).
