Check your cacti log for any errors. Post the SYSTEM STATS line from the log.

It seems to happen on a regular interval. Is it just this graph or is it happening to a lot of graphs? What Cacti version?

You may have to watch the server and see if anything else is going on during that time and if it is impacting CPU or iowait (writing to disk) on the Cacti server.

All other images are fine, only this VLANIF graph has an issue.
