The global size of log files is set like other configuration items and controlled by the LogSize variable. You can set this variable with the command-line interface but not with the administration GUI; however, you can use the administration GUI to set the size of the log file for a specific Screen. The default log size is 100MB, but it is configurable. If the log file fills up, it will overwrite the oldest data and information can be lost.
The log file for a Screen is resized only when that Screen is restarted.
