Server Keeps Crashing

Step 1: Check the Crash Log

Go to Dashboard → Server → Console and scroll up to find error messages. Common patterns:

• "OutOfMemoryError" or "OOM" → Server needs more RAM. Upgrade your plan.
• "StackOverflow" → Usually caused by a broken mod or plugin
• "Segmentation Fault" → Game server binary issue, try reinstalling
• "Permission Denied" → File permissions issue, contact support
• "Port already in use" → Another process using the port, restart the container
• "Unable to access jarfile" → Corrupted server files, reinstall

Step 2: Check Resource Usage

In Dashboard → Server → Overview, check:

• RAM usage — If consistently above 90%, upgrade
• CPU usage — If peaking at 100%, upgrade to a higher plan
• Storage — If full, server can't save and will crash

Step 3: Recently Added Mods?

If you recently added mods, try:

1. Remove the last mod you added
2. Restart the server
3. If stable, the mod was the issue
4. Check mod compatibility and version requirements
5. Add mods back one by one to find the problematic one

Step 4: Check for Corrupted World Data

• Try restoring from a recent backup
• For Minecraft: delete level.dat_old and check region files
• For Rust: reset map with a new seed
• For ARK: verify save files aren't corrupted

Step 5: Try Vanilla

If nothing works:

1. Create a backup of your server
2. Reinstall the server (fresh install)
3. Test without any mods
4. Add mods back one by one

Auto-Restart (Watchdog)

GameHostCloud automatically restarts crashed servers within 30 seconds. If your server crashes repeatedly (5+ times in 10 minutes), the watchdog will pause and you'll get a notification.
