Customers that have floating licenses (ie. that use the FlexNet license manager) may want to consider occasionally backing up or deleting the license manager log files. If you have a lot of licenses that are very actively used, the log files can grow quite large. Large log files aren’t a major problem, but eventually they can consume a significant amount of disk space. They can also make the FlexNet web dashboard rather slow.
You can find the location of the log files on the following KB page.
