    Add a watchdog counter or something similar into the shared memory header. If the counter fails to update, initiate UFO.

    If PIBufSS crashes, data loss can occur.  implement something that allows UniInt to know that the Buffer Subsystem is not responding and initiate failover if available.

    This was previously enhancement 119481.
