osrm-extract fails with very large size raster file. #5571
Description
When we execute osrm-extract with very large raster file, osrm-exract consume too much memory and failed to finish execution.
For example...
raster_source = raster:load(
"kanto13_ascii_osrm.asc", -- file to load
137.81250000000003, -- longitude min
141.328125, -- longitude max
34.88593094075317, -- latitude min
36.597889133070225, -- latitude max
24576, -- number of rows
40960 -- number of columns
When I try to use raster file which size is 40960 x 24576 (zoom = 13 for whole Kanto (in Japan) area), I could not success the osrm-exract.
osrm-exract read more the one times and fails with below log message.
