[gdal-dev] Excessive memory usage in python script

[Frank Warmerdam]

>   format = "GTiff"
>   outdataset.driver.Create(outfile, inband.XSize, inband.YSize, 1, 
> gdal.GDT_Float32)
>   outband = outdataset.GetRasterBand(1)

Jamie,

I'm very suspicious about the above, and I *suspect* it is orphaning
the new dataset objects created with the Create() call which might
be responsible for your resource leak.

I would suggest:

   format = "GTiff"
   outdataset = gdal.GetDriverByName(format).Create(....)

Good luck,
