Open tingzhenli opened 4 years ago

tingzhenli commented 4 years ago

In my centos7(memory:32G):

  1. docker run -it --name ctb -v "/data/maping/to3dtile/dsm":"/data" tumgis/ctb-quantized-mesh
  2. ctb-tile -f Mesh -C -N -o out dsm.tif note: the dsm.tif is 82MBytes from opendronemap
  3. It uses 2minutes to finish the above process
  4. ctb-tile -f Mesh -C -N -l -o out dsm.tif
  5. The computer memory used by ctb-tile increase to > 90% and core dump
  6. Test data

I fix it:

  1. ctb-tile -f Mesh -C -N -l -o out dsm.tif ====> ctb-tile -c 1 -f Mesh -C -N -l -o out dsm.tif so, there must has a mulit-thread problem.

@tingzhenli thank you for the workaround, I've been struggling with this core dump issue for a while
