Hi All, I am working on fixing a memory use issue in the Virtual Planet Builder project (an off shoot of OpenSceneGraph) and have come accross the exact issue described in this thread.
The code essential runs in a loop creating an image pyramid from a large ECW file. During this loop there a very large number of RasterIO() calls. When doing this memory use grows continually, seemingly without limit. If I close and repoen my GDALDataSet regulary then I regain all the memory but it seems from this thread there should be a much better way to control memory use. I have tried calling GDALSetCacheMax() with values from 1 to 1,000,000 with no effect. I have also tried calling while(GDALFlushCacheBlock()); after each RasterIO call, once again with no effect. I am hoping somebody could point me in the right direction because I am running out of ideas.
