[hobbit] White holes in xymon graphs

This is the same thing I have been getting except my holes are only for one 5 minute interval and then repeats exactly 1 hour later, 2 hours later and sometimes 3 hours later. No messages, and other trending do not show any issue.

I've seen random holes caused by data being sent to the server twice (happends if you interconnect multiple hobbit servers), but these leave messages in rrd-status.log like "illegal update, minimum update delay is 1 second".

Is the data really sent every 5 minutes? It could be delayed by some (other) cronjob, and then get associated to the wrong time slot.
