Issue Details

I have NI Volume License Manager 3.1.2 or previous and my nilm.log is currently growing and filling up all our available space. Is there a way to stop this log from continuously growing?


This is a known issue in previous versions of Volume License Manager (VLM) version 3.1.2 and older. To stop this file from growing continuously, update your Volume License Manager to at least version 3.2 or newer.

Additional Information

Before updating your version of Volume License Manager, it is recommended you backup your configuration settings on the current installation prior to beginning the upgrade.
