First of all, I wanted to thank Hashim Mundol for showing me this awesome tip. As everyone knows, when you stop and start the license server with lmtools, the log file will be overwritten so you will not know what happened before you stopped the service.
To append the log file results easily, just add a + sign to the Path to the debug log file.
You can also do this the hard way by creating an options file as well. It is on page 158 of the License Administratrion Guide (11.12.0).
