2.3. Log files can exhaust local disk space

Description

A long-running license server may fail because the license server log files flexnetls.log and access.log have exhausted the disk space on the server. Although the license server rotates log files by opening a new log file each day, it does not automatically delete old log files.

Workaround

Delete old log files when they are no longer required. On Linux, you can use a cron job to delete files that are more than a specific number of days old.
