Min, The problem he's seeing has something to do with his server being overloaded, the poller is not being able to poll each host interface every 5 minutes.
That whats causing the gaps. The server becomes slow with that many pollers running and we can't update every 5 minutes. Modifying the RRA parameters is not a fix for this.
