I am new to this forum, and new to Cumulus.
We are an importer for the WH1080 weather station.
We are running a demo of Cumulus from our website
http://www.signatrol.com/weather/index.htm
Please note that the wind data will not be sensible, as we have the sensor mounted close to a building.
But the cumulus software is crashing every few days and uploading flat line graphs to the our web site.
The bugreport identifies the error as:
exception class : ERangeError
exception message : Range check error.
Full bug report attached.
I've attached the screen shoot of the problem, i've reset culumus and you can see the trends recover.

Any help Welcome.
Regards
Nick Price
