Game crashes randomly with a Segmentation Fault on Linux #2681

Your system information

gist attached

OS: Arch Linux x86_64 Host: MS-7D78 1.0 Kernel: 6.8.1-arch1-1 Packages: 659 (pacman) Resolution: 2560x1440 DE: Hyprland CPU: AMD Ryzen 7 7700X (16) @ 5.573GHz GPU: AMD ATI Radeon RX 7700 XT / 7800 XT

Please describe your issue in as much detail as possible:

The game crashes randomly while playing a match in dota. It can happen randomly after 1 min of gameplay or 20 mins of gameplay. The most I could get out of the game without it crashing with a segfault was 30 mins. Sometimes it crashes more than 4 times in a span of 10 minutes. I verified my game files multiple times. I also changed my operating system to Pop OS (Debian based), Nobara (Fedora based) and Arch Linux. The problem was consistent with all of these. I even tried adding 'WAYLAND_DISPLAY= %command% -vulkan' to my launch options. Did not help.

Steps for reproducing this issue:

  1. Start the game up normally.
  2. Play the game normally.
  3. Wait for it to crash.

For reference, the attached minidump is a SIGSEGV in libparticles.so.

Is there a way to fix/patch it on my end?

Someone on here suggested running valgrind on the library path. Is this VAC safe?

Had the same thing, switched to Proton Experimental and DX11 no problems.

This problem was fixed after the the vm.max_map_count parameter was increased from the default 65530 value to 1048576 on Arch Linux.

No more random crashes anymore. Apparently this change was pushed to all major Linux releases (I checked Fedora, SteamOS and Arch).

Thanks for your help @kisak-valve ! Cheers!
