CircularLogSize

Use this option to specify the maximum size of the system_name_timestamp_host_name.log file.

When the log file reaches the maximum size, the Launcher service closes it, appends an index number to the timestamp in the log file name (LauncherLog_timestamp_index.log), and begins logging to a new file.

Description
n
The maximum log file size. The maximum size is 100 MB. A value of 0 specifies an unlimited log file size.

The default minimum size is 10 MB. If you specify a smaller size than 10 MB, the Launcher service creates a 10 MB log file.
