Maximum file size? WebControl stops with KeyError Session is disconnected

Morning,

I am trying to carve a fairly complex Gcode file (15MB uncompressed) and upon uploading I get the above mention. Is this due to the file size, due to the computer that runs WebControl, or is there another possible error?

Thanks
