When the JVM application is idle for log periods of time, the Wrapper by default will close its log file so it can be deleted or manipulated in other ways.
This property controls the number of seconds since the last log entry after which the log file will be closed.
Possible values are in the range of "0" to "3600" seconds.
A value of "0" (zero) will cause the log file to be closed immediately after each log entry is written to disk.
The default value is "1" second.
When the log file is closed, any unflushed log output will be flushed automatically.
