How to Fix Exit Code 137 (Out of Memory Error)

Aug 22, 2025 ValueGameNode 28

This guide explains how to fix exit code 137. This error is caused by insufficient RAM and can be solved by either optimizing your server or upgrading your plan.

Symptoms

  • Your game server abruptly stops or crashes.

  • The server console shows the message exit code 137.

Cause

The exit code 137 occurs when the server's RAM (Random Access Memory) is fully consumed. The system terminates the server process to prevent instability. This is often caused by a high number of players, resource-intensive plugins/mods, or a large world size.

Solution

You have two options to fix this issue. We recommend trying Option 1 first.

Option 1: Optimize Your Server

Try to lower your server's RAM usage with these steps:

  • Remove Unnecessary Plugins/Mods: Deactivate and delete any plugins or mods that are not essential for your server.

  • Reduce View Distance: Lowering the view-distance in your server's configuration files can significantly reduce memory consumption.

  • Limit World Size: If your world is excessively large, consider using a world border or trimming unused chunks.

Option 2: Upgrade Your Plan

If optimization doesn't solve the problem, or you simply need more power for your community, the guaranteed solution is to upgrade your plan.

Steps to Upgrade Your Plan:

  1. Log into the Client Panel and navigate to your service.

  2. Click the Manage button.

  3. In the Upgrades & Add-ons section, select Change Plan.

  4. Choose a new plan with more RAM to instantly upgrade your server.
