Distro / Kernel release: Debian GNU/Linux 11 (bullseye) / 5.10.0-8-amd64 Mono / .NET package version: mono-complete (6.12.0.122 from www.mono-project.com) Graphics driver version: Mesa 20.3.5-1 [Intel HD Graphics 6000 (BDW GT3) (0x1626)] Works for client, mp server or both: Client, server untested Installation method used: tar zxvf vs_archive_*.tar.gz (no need to use install.sh script) Hacks (if needed): crash due to memory issue, see below Vintage version: 1.16.4 For mono installation I followed: https://www.mono-project.com/download/stable/#download-lin-debian (took Debian 10 settings, I'm on Debian 11 but that worked fine) After launching run.sh, I experienced systematic crashes when joining a Multiplayer game. In output traces I could see: * Assertion at lock-free-alloc.c:145, condition `sb_header' not met, function:alloc_sb, Failed to allocate memory for the lock free allocator Found solution here: https://github.com/anegostudios/VintageStory-Issues/issues/1742 https://github.com/mono/mono/issues/12947 As root user: # sysctl vm.max_map_count vm.max_map_count = 65530 # sysctl -w vm.max_map_count=262144 vm.max_map_count = 262144 # sysctl vm.max_map_count vm.max_map_count = 262144 So increasing soft limit from 65530 to 262144 fixed my issue.
