Has NX implemented the TIMEOUT feature in FlexNet? Haven't followed NX licensing for a few years, but when TIMEOUT was introduced, UG2/NX did not support its use.
I don't see anything in the option file options that will do what you want. I am guessing you have more users than licenses? Not sure if gROUP will provide some of what you want.
Check out the FlexNet Licensing End User Guide for details of the options.
