Why does MATLAB timeout while running long calculation in "nodesktop" mode?

I am running a MATLAB job with "–nodisplay", "–nodesktop" options. While running a regression on MATLAB, I have noticed that it was aborting after a specific time period. The problem was debugged to the license server revoking the MATLAB session's license after a specific timeout (12 hours) as the session was being marked as idle.
Why is the session being marked as idle although it is still executing a script? Below are my MATLAB logs.
2019-02-05 13:23:26 (MLM) OUT: "Signal_Toolbox" username@hostname
*2019-02-06 01:20:14 (MLM) Idle session. Returning keys for username@hostname.*
2019-02-06 01:20:14 (MLM) IN: "Communication_Toolbox" username@hostname
