FLEXnet has been improved from version to version to make report logging more robust. Nevertheless, particularly in older versions of the vendor daemon, corruption can occur in the report log.

Follow these guidelines to avoid corrupt report log files:

• In pre v 5.1 vendor daemons, rereads, and shutdowns could possibly introduce corruption, particularly if the server is busy. With these older vendor daemons, the best policy is to issue a reread or shutdown when no licenses are checked out, if possible.
• Issuing an lmdown command while the server is shutting down can cause corruption.
• Don't move, copy, or edit the report log file while the server is running.
• Never configure more than one license server to write to the same report log file. In the case of a redundant server, each vendor daemon must write to a distinct file, preferably one that is local to the server machine. Even if the report log is not corrupted, SAMreport-Lite will not run a report using a report log that has been written by a vendor daemon running on more than one license server machine.
• Never configure different vendor daemons to write to the same report log file. Even if the report log is not corrupted, SAMreport-Lite will not run a report using a report log that has been written by more than one vendor daemon.
• Do not use lmswitchr or -switchlog to switch the report log to an existing report log file. Switch to a file with a new name.
• Never hand-edit a report log or combine report logs together into the same file.
• If you change a server host name, make sure you stop the license manager and create a new report log when the name change is complete.
