So, my attempts continue to get mapnik rendering the benchmarking datasets used in the Geoserver vs. Mapserver tests (http://blog.geoserver.org/2008/10/22/geoserver-benchmarks-at-foss4g-2008/ ).
In trying to render a 200MB gdal layer in Mr Sid format I get the following error with mapnik build in DEBUG: size = 2 file=S-34-30_2000/S-34-30_2000.sid type=gdal datasource=0x36d130 type=1 name=gdal encoding=utf-8 layer1 - > Envelope(160576.125,-3875914.625,839403.375,-3317784.875) layer2 - > Envelope(160576.125,-3875914.625,839403.375,-3317784.875) scale=1395.32 start map processing bbox=Envelope(81392.4375,-3875914.625,918587.0625,-3317784.875) scale denominator = 5.54739e+11 start layer processing : S-34-30_2000 datasource = 0x36d130 Block=1024x128 Type=Byte Color=Red Block=1024x128 Type=Byte Color=Green Block=1024x128 Type=Byte Color=Blue Python(36546) malloc: *** mmap(size=3168227328) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug 0.01 s MemoryError close connection 0x895200 I think other users have run into memory errors like this when using a gdal layer, but I've not seen any workarounds. Short of doing malloc debugging like the error hints, I may trying converting to tiff. Anyone else have suggestions?
