--- Comment #1 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> ---
Unfortunately, the removal of code doing re-announcements on the basis of
packet counter, according to RFC 3954, is forbidden[1], so maybe our
respectable programmers can fix it. 

[1]   3. On a regular basis, the Exporter MUST send all the Template
      Records and Options Template Records to refresh the Collector.
      Template IDs have a limited lifetime at the Collector and MUST be
      periodically refreshed.  Two approaches are taken to make sure
      that Templates get refreshed at the Collector:
            * Every N number of Export Packets.
            * On a time basis, so every N number of minutes.
      Both options MUST be configurable by the user on the Exporter.
      When one of these expiry conditions is met, the Exporter MUST send
      the Template FlowSet and Options Template.
