MATLAB error when PC idle: render process terminated: null

I am getting following error when I kept MATLAB idle for long hours (No codes running, overnight). I am using 2021a version (academic license). I am not sure this error is interfering anywhere while runnning codes or simulink.

render process terminated: null

java.lang.NoSuchFieldError: TS_PROCESS_OOM

Hi Praveen,

The error you are encountering seems to be sporadic and may be caused by MATLAB running out of memory.

To address this issue, I recommend increasing the allocated heap size for MATLAB. To do so, please follow these steps:

1. On the "Home" tab, in the "Environment" section, click "Preferences". Select "MATLAB" > "General" > "Java Heap Memory".
2. Select a value using the slider or spin box.
3. Click "Ok".
4. Restart MATLAB.

For more details, kindly refer to the following MathWorks documentation page:

Java Heap Memory Preferences - https://www.mathworks.com/help/releases/R2021a/matlab/matlab_external/java-heap-memory-preferences.html

Hope this helps!
