Conan Exiles Dedicated Server Crashing - Diagnosis & Fixes
A Conan Exiles dedicated server crashing in 2026 typically falls into one of four patterns: mod conflicts, memory exhaustion from large player-built structures, BattlEye-related boot failures, and Wine-layer issues on Linux hosts. This guide walks through each pattern with log signatures and the practical fix.
First diagnostic step: grab the latest log from ConanSandbox/Saved/Logs/. Conan Exiles logs are verbose and almost always show the cause of a crash in the last 100-200 lines. Without the log, you're guessing.
If the crashes started after 15 September 2026, check your build first. Patch 2.2.0 moved Conan Exiles Enhanced to Unreal Engine 5.8.2 and replaced the UE4 networking model with Iris, and it introduced server crashes that Funcom hotfixed on 17 September with "Fixed several server crash issues". The same hotfix fixed servers wrongly asking for a password when the player had previously made a passworded coop game, which reads like a login failure rather than a crash. Update to a build newer than 17 September before working through the four patterns below, or you may be diagnosing a bug that no longer exists.
Crash Pattern 1: Mod Conflict
By far the most common cause. A mod that worked last patch breaks after a Funcom update; OR two mods touch the same scripted hook and step on each other.
Symptom in log:
Mod XYZ failed to loadNullReferenceExceptionfollowed by a script path containing a mod ID- Crashes 30-90 seconds after world load (right when mod scripts initialize)
Fix: Disable mods one at a time via modlist.txt. Restart between each change. The biggest offenders historically are large overhaul mods (Hosav's UI, Stacksize, Pippi) that depend on specific game versions. If a mod author hasn't pushed an update for the current Conan patch, remove that mod and wait.
For mod loading mechanics see Conan Exiles mods installation.
Crash Pattern 2: Out of Memory from Large Builds
Conan Exiles' simulation gets heavier as players build big. Once your server's structure count crosses ~100,000 placed pieces, memory usage spikes during area-of-effect calculations (decay sweep, raid damage) and the server can OOM.
Symptom:
OutOfMemoryErrororstd::bad_allocin the Unreal log- Server crashes during decay sweep or raid window
- OS kills the process with OOM-killer messages in
dmesg
Fix:
- Increase RAM allocation. Conan's baseline is moderate; mature server RAM creep is real. If you're hitting OOM, your VPS plan has outgrown its purpose.
- Consider building rate-limits or anti-grief systems via mods like Pippi or admin commands
- Run a periodic structure-prune RCON command targeting abandoned builds
Crash Pattern 3: BattlEye Boot Failure
BattlEye sometimes fails to initialize on startup, especially after a patch that changed BE files. The server appears to start but crashes within the first minute.
Symptom:
BattlEye initialization failed- Server reboots in a loop without ever reaching steady state
Fix:
- Re-validate the server install:
steamcmd +login anonymous +force_install_dir [path] +app_update 443030 validate +quit - If you're running mods that need BattlEye exemptions, your
BattlEye/scripts.txtmay need updates after the patch - check community Discord channels for the current exemption list - For testing only, you can disable BattlEye with
-NoBattlEyelaunch arg, but don't run a public server without anti-cheat
Crash Pattern 4: Wine Layer (Linux Hosts)
Conan Exiles' dedicated server is a Windows binary. Linux hosts run it through Wine. Wine-related crashes appear differently from Windows-native ones.
Symptom:
wine: Unhandled page faultin the wine logfixme:messages flooding the log just before the crash- Server starts cleanly on Windows but crashes on Linux+Wine
Fix:
- Use a current stable Wine (or Wine staging). Older Wine versions miss .NET fixes Conan needs
- Install winetricks dependencies:
winetricks dotnet48 vcrun2019 - Some hosts use GE Proton instead of vanilla Wine for better game compatibility
- If you've custom-tweaked your Wine prefix, try a fresh prefix to rule out stale config
Quick-Diagnosis Decision Tree
| Crash timing | Likely cause | First check |
|---|---|---|
| 30-90 seconds after world load | Mod conflict | Disable mods one at a time |
| During decay sweep / raid window / "30-min mark" | OOM from large structure count | Check dmesg for OOM-killer |
| Within first minute of every restart | BattlEye init | Re-validate install; check BE script exemptions |
| Linux only, runs fine on Windows | Wine layer | Update Wine; install dotnet48 + vcrun2019 |
Recovery After a Crash
Conan Exiles crashes occasionally corrupt the world database. Recovery options:
- Restore the previous
game.dbbackup. The server creates rotating backups by default - checkConanSandbox/Saved/ - For minor corruption, use the SQL repair commands documented in the official Conan Exiles wiki
- If neither works, restore from your last clean snapshot (managed hosts have these; self-hosts need a snapshot script)
Long-Term Crash Prevention
- Set up rolling backups every 30 minutes
- Stay one version behind unstable mods rather than chasing every release
- Watch the Conan Exiles official forum for known-bad patches before updating
- Run a periodic structure-decay check to prevent runaway build counts
