• Closed as program error.

Error description

• Want to add a configurable variability to Personalization query
  cache timeouts to fix the scenario of multiple pzn portlets on
  the same page all having their cache entries timeout at the same
  time.  With this variability the case of all the portlets all
  having their cache expired at the same time is very rare and
  would require that the page wasn't hit by the users in (timeout
  + (timeout * variability)) time.
