  ****************************************************************
  * RECOMMENDATION:                                              *
  * added a configuration option called 'DoNotPrune' that should *
  * be used with pollers that should not prune.  So if multiple  *
  * pollers are configured to run, add 'DoNotPrune' to all the   *
  * other pollers except for one,  by default all pollers will   *
  * continue to try and prune data unless DoNotPrune option is   *
  * used                                                         *
