[mrtg] False MRTG Graph

With a 5-min interval and 32bit counters, you get rollover at about 110Mbits/s and the graphs go wrong.
So, with a 1-min interval and 32bit counters, this would be at 550Mbps.
Hmm, suspiciously similar!
I suspect you are using 32bit counters, even if you think you aren't. Make sure you have :::::2 at the end of the Target definition. Post the Target definition here (obfuscate the SNMP community of course) if you still can't solve it so people can take a look.

I Am facing a strange problem, As I have attached a png file of my WAN GIGA Interface of my Zyxel Router, Problem is that when ever our Internet Bandwidth cross over 555 Mbits/s MRTG creates False Graphs, but on real time monitoring Show more then 600 Mbits/s of data flowing normally thought it, I am using SNMP v2 to create MRTG , also have applied 1min MRTG patch to create MRTG. I have CHeck router cpu and memory and other Interfaces are working normally and there MRTG matched the real time flow.
