Solving "ESO Lua Reaching Memory Limit" Issues

When Lua code is running within Elder Scrolls Online (ESO), it is sometimes necessary to exceed the default memory limits. When the script reaches its maximum memory limit, a fatal error occurs and the script is stopped. This article will provide valuable and relevant information to my developer persona and step-by-step instructions on how to resolve ESO Lua reaching memory limit issues to ensure that scripts run without interruption.

Adjust Configuration File

The primary way to rectify a memory leak in ESO is to adjust the configuration file. Access the configuration file by navigating to the Documents folder and the Elder Scrolls Online directory. Then locate the UserSettings.txt file and open it with a text editor. Look for the value LuaMemoryLimit on the fifth line and change it to a new number. By setting the LuaMemoryLimit to a higher value, the script will allow more memory and the limit will not be reached quickly.

Test Memory

Adjustments to the LuaMemoryLimit value may cause undesired side effects. After changing the value, it is best to test the script to make sure that the issue is resolved. Run the script a few times, and monitor the status of the system. If the script still reaches the memory limit, try a higher setting in the UserSettings.txt file.

Monitor Garbage Collection

Garbage collection performs memory maintenance by cleaning up unreferenced objects and clearing out unnecessary data. It is important to keep an eye on garbage collection to ensure that scripts are running efficiently. When the garbage collection process starts, the total allocated memory will increase. If the total allocated memory keeps increasing, then the garbage collection process may need to be improved to boost the performance of the script.

Debug Script

If all of the previous methods fail, it is possible to debug the script. Look for any inefficient loops or redundant code which could be causing a memory leak. Look for any global variables that may be consuming additional memory and optimize them if possible.


How do I increase the memory limit for Lua code?

The primary way to increase the memory limit for Lua code is to adjust the configuration file. Navigate to Documents/Elder Scrolls Online/UserSettings.txt, open the file with a text editor, and look for the value LuaMemoryLimit. Change the value to a higher number to increase the memory limit.

What should I do if the script is still reaching the memory limit?

If the script is still reaching the maximum limit, try utilizing a higher value for LuaMemoryLimit in the configuration file.  Additionally, it may be helpful to debug the script, look for inefficient loops, and optimize any global variables that may be consuming additional memory.

What are some common signs of a memory leak?

Common signs of a memory leak include the script running slowly, lagging or stalling, or crashing completely. Keeping an eye on the total allocated memory while running the script may also be helpful; if the total allocated memory keeps increasing, then the garbage collection process may need to be improved to boost the performance of the script.

What is garbage collection?

Garbage collection is a memory maintenance process that cleans up unreferenced objects and clears out unnecessary data. This process is important when running ESO Lua scripts to ensure that it does not reach its memory limit.

Are there any other methods to increase a script's memory limit?

Aside from adjusting the LuaMemoryLimit parameter in the configuration file, there are no other methods to increase script's memory limit. However, debugging the script, eliminating inefficient loops, and optimizing global variables will help decrease the strain on the script's memory allocation.

Improve garbage collection performance?

To improve garbage collection performance, try writing efficient code, reduce the number of objects being created and terminated, and avoid global variables where possible. Additionally, it can be helpful to monitor the garbage collection progress while debugging. Monitoring the garbage collector will help identify if the issue is caused by code or by the collection itself.
