Star Citizen fails during PU loading or hangar traversal on Linux/Nobara

Tracked since 18 Aug 2026 · Last researched 18 Aug 2026

Problem

Star Citizen fails by freezing or exiting without showing the crash handler on a Nobara Linux system during PU loading or hangar traversal. These checks are relevant only when a local log or system monitor also suggests memory pressure or a host resource limit.

This is a conditional path for players already using an unsupported Linux setup, not a general fix for every Star Citizen crash.

Applies to Alpha 4.9.x LIVE · Current

Fallback only

Add a filesystem-compatible swapfile alongside zram

Use a filesystem-compatible physical swapfile alongside zram only after memory pressure or a host limit is relevant; this is a Limited-support path for an unsupported Linux setup.

Use this as the least invasive part of the combined memory configuration after confirming that memory pressure or a host limit is relevant.

What to do

  1. Check the current memory and swap state with free -h, zramctl, and swapon --show.
  2. Keep zram enabled where appropriate and add a filesystem-compatible physical swapfile using your distro and filesystem documentation.
  3. For Btrfs, use the native btrfs filesystem mkswapfile path or the documented equivalent; do not use a generic sparse swapfile.
  4. Verify the swap is active, then retry the same loading or hangar state while watching the game log.

The result remains Limited support because the intervention combined multiple changes and the swapfile's effect has not been isolated in Alpha 4.9 Nobara.

Limited SupportMedium riskAlpha 4.9.x LIVE single-system report plus current LUG guidance; exact build unresolved

Other options

Run the LUG Helper preflight check

Use the preflight check to identify low memory-map or open-file limits before making manual host changes. A pass does not prove the crash is fixed.

Steps

  1. Run the LUG Helper preflight check.
  2. Inspect the vm.max_map_count and hard open-file limit results.
  3. Use only the documented, understood remediation for a failed check, then verify the resulting values.

This is a prerequisite check, not a direct crash recovery.

Limited SupportLow riskCurrent Linux specialist guidance; not an exact 4.9 crash reproduction

What not to try

Do not copy the sysctl deletion recipe blindly

High risk

Do not paste the sysctl deletion recipe or force its extreme vm.max_map_count value. Those system-wide changes are invasive, outside RSI's supported Linux platform, and were not isolated as the cause of improvement.
