=======================================================
Increase the sysctl option vm.max_map_count to prevent
crashes due to memory allocation limits in areas with
lots of geometry:
Note I am running at 4K on 64GB RAM so my setting is 2100000000
For anyone running 1440p or 1080p with upto 32GB RAM use 16777216

sudo nano /etc/sysctl.conf
enter the sysctl option vm.max_map_count

vm.max_map_count = 2100000000

sudo nano /etc/sysctl.d/20-max_map_count.conf
enter the sysctl option vm.max_map_count to prevent crashes
due to memory allocation limits in areas with lots of geometry
vm.max_map_count = 2100000000

sudo nano /etc/systemd/system.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000

sudo nano /etc/systemd/user.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000

To temporarily increase this value enter this command in a terminal
sudo sysctl -w vm.max_map_count=2100000000

Output: vm.max_map_count = 2100000000
