Thanks for your answer Alex.

I think that it's MRTG's problem, because that time every day is the 'peak hour' for my customer's bandwidth... Also, the Threshold check is on his peak traffic utilization... 11.5Gb.. too many coincidence... believe, the easiest thing for me is to say to my boss "no fault found on my mrtg graphs"... but i have to prove it.. :P

Well, the problem exists on the aggregated graphs.. if you see the graphs of each 10gig interface separately, it seems that everything is working fine, but on aggregated graph i have this strange behavior!
