Specifies, in seconds, the polling interval the CI port driver
    uses to poll for a newly booted computer, a broken port-to-port
    virtual circuit, or a failed remote computer.

    This parameter trades polling overhead against quick response to
    virtual circuit failures. VSI recommends that you use the default
    value for this parameter.

    VSI recommends that you set this parameter to the same value on
    each cluster computer.

    PAPOLLINTERVAL is a DYNAMIC parameter.
