[8.0H4] linux post-exit crash (not an issue for game but builds up gigs of core dump logs)

[rudi_pioneer]

X4 consistently crashes on exit, which is fine for the game, but i've realized that keeps creating few Gb dump logs every time.

I think it's harmless because steam successfully syncs savegames after, i'm able to open game again and play normally, and some googling says this is vulkan clean up race condition.

This is less urgent it seems that fedora has default limits

- MaxUse= — defaults to 10% of the filesystem size
- KeepFree= — defaults to 15% of the filesystem free space

So it can't eat up all SSD space

On Fedora, this turns off core dump, which is fine since i mostly play games on it

Code: Select all

  sudo mkdir -p /etc/systemd/coredump.conf.d                                                                                                                                                         
  cat <<'EOF' | sudo tee /etc/systemd/coredump.conf.d/disable.conf
  [Coredump]
  Storage=none
  EOF

Can confirm this is an issue in 9.0B4 as well. Consistent coredump on exit. I'm on Arch and using the Steam version of the game, running on Wayland. Same behavior on both native Wayland and x11 SDL settings. Like mentioned in the OP: Not a huge issue, just somewhat annoying when you need to relaunch the game often (such as checking mods or developing mods).
