    * 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                                                         *
