Does anyone have DayZ running on Gentoo ~amd64? I have everything installed. Launcher opens. When i go to launch a server the load screen starts and then it crashes.

I have the game Vigor running fine. I need to see if this happens with any others.

I haven't played it in a while, but it would crash like that before bumping up vm.max_map_count.

You can check what it's currently set to with:
Code:
 sysctl vm.max_map_count

And change it with:
Code:
sysctl -w vm.max_map_count=524288

you can add it to /etc/sysctl.conf if you want the change to persist through a reboot.
Here is a good table for choosing a value to use.

Some distros yeet it right up to 1048576...

This is exactly what it was. Thank you.

This is also documented on the wiki : https://wiki.gentoo.org/wiki/Steam/Client_troubleshooting#Increase_virtual_memory_mapping
Recently Arch Linux also increase this value : https://archlinux.org/news/increasing-the-default-vmmax_map_count-value/
