Does this happen only on one graph, or do all the graphs gap? Have you changed the snmp cycle time from its default for this device? Is there a max value set on the data point for this device?
My first guess would be that there is a maximum value set on the data point, and when an RPN transform is done on the value, it exceeds that value. You can use: rrdtool info /path/to/rrdfile/ifInOctets_ifInOctets.rrd | grep "^ds" to view the configuration of the rrd file. It will show if there is any min or max values set and what the update time is (steps = 300 = 5mins, etc). Additionally, the heartbeats value may be of interest. It should be three times the step time. If you do not get a value within that minimal_heartbeat, you will get a gap. The default is 15 minutes (900).
