Obj2Tiles conversion Memory leakage

[sarath7974]

We ran Obj2Tiles conversion for a model of size 470 mb . At the step of writing to tiles, obj2tiles library consuming memory of 60GB RAM and 60 GB SWAP Memory and got killed at end due to OOM issue

The machine configuration is a 60GB RAM system and Version of Obj2Tiles used : v1.0.11.
The RAM memory gets fully consumed while running the command and gets killed automatically.

Command used for conversion : Obj2Tiles input_dir/model_name.obj ./output_dir

Model files to reproduce the issue : https://drive.google.com/file/d/1kLltbY4pNS3Zk_AzRMV1Svn9lD25dhxu/view?usp=sharing

Anyone have any possible explanation on why it is getting killed.
