When the machine's RAM usage is high, the Nintex Studio application may occasionally crash.
To help prevent this, you can reduce the Nintex RPA RAM usage threshold from the default 20% to 10%.

Instructions 
Please navigate to the folder Path: C:\Program Files\Nintex RPA Studio\Config\appSettings.config
Note: Before making any changes, please ensure you take a backup of the appSettings.config file:
 

*Open the appSettings.config file in Notepad and look for the following entry:
<add key="FreeMemoryPrecentageThreshold" value="20"/>

If the entry is not present, add this line at the bottom of the file (within the <add> entries):
<add key="FreeMemoryPrecentageThreshold" value="10"/>
 

Please update the value from 20 to 10 (or adjust as needed). We recommend not setting it too low, as that could cause Studio to crash. After saving the changes, restart the machine to apply them.
