Thankyou, you have just explained a really pernicious bug in the
routers2.cgi trending analysis module. Since the trending analysis also
uses a similar method to generate a tempoary RRD file, it is being affected
by this -- I just could not work out how some people were getting this
behaviour (negative, and spiked results in the trending graph). So, it
appears it is a bug in later versions of RRD for windows.
I wonder if Tobi knows about this?
