Hi Dan, I apologise for the late reply: coulc you please save the ntop log in a file and sned it to me so that I can see whether there's something strange when the dropoff happens? Do you have an idea what's the cause of the problem? How didi you draw the graphs, using the ntop Perl/PHP interface ?
