    * RECOMMENDATION: Apply the PTF if you use the z/VSE virtual   *
    *                 tape (VTAPE) support.                        *
    ****************************************************************
    The VTAPE STOP processing frees some control blocks before
    clearing the respective pointers. Under rare circumstances
    this may cause a hard wait FFB, when another task (e.g. the
    service system task) performs I/O against the virtual device
    that is being terminated.
    

Problem conclusion

  • The PTF fixes a code logic error that may cause a hardwait FFB.
