The FlexNet license server daemons log messages about the state of the license server hosts, and when licenses are checked in or out. This log helps to resolve problems with the license server hosts and to track license use. The log file grows over time. You can remove or rename the existing FlexNet log file at any time.
You must choose a location for the log file when you start the license daemon. If you already have FlexNet server running for other products and Platform LSF licenses are added to the existing license file, then the log messages for FlexNet should go to the same log file you set up for other products. If FlexNet is dedicated to managing LSF licenses, you can put the FlexNet log in the same directory as your other system logs, or in the /tmp directory.
