Web based results, using TPad->Print(filename)

I have a root based process that runs in the background gathering data. Once every 15 seconds, it ‘prints’ a gif of the current TGraph objects as they are drawn onto a TCanvas.

Within a few hours of starting this process up, it consumes 90% of the CPU. If I comment out the line that does the print (save as exhibits the same problem), the process runs at <1% average CPU.

Any particular hints on why this might happen or how I might do it differently?


Could you identify your version of ROOT? Several fixes in Print were applied in the past few months.


I am using 5.26/00. Should I grab the development version?
