"UNSUPPORTED: License server system does not support this feature” in lmgrd Log

Issue Details

After installing a new license file on my volume license server, my lmgrd log contains many messages of the form:
13:25:31 (nilm) UNSUPPORTED: "LabVIEW_Core" (CF14901C7384) user@COMPUTER
(License server system does not support this feature. (-18,327)) 
Do these messages indicate an error?

Solution

This type of message writes to the lmgrd log when you install a new license file on NI Volume License Manager (VLM).  Most licensed NI software is designed to communicate with the volume license server at regular intervals.  When the license file is updated on the server, it loads information from the new license file.  However, any client software that remained open during the license swap uses the server data it received when the license was checked out.  Thus, each transmission the client sends contains data that no longer matches what is on the server resulting in the message.

These messages have no effect on client software.  The messages will continue to be logged until client software that was open during the license swap has been restarted.

You may also notice messages like:
13:26:47 (nilm) Checkin failed feature "LabVIEW_AppBuilder": user COMPUTER
13:26:47 (nilm) "No such feature exists. (-5,346)"
These messages occur when client software that was open during the license swap is closed.  These messages are also benign and occur for the same reasons previously described.
