FWSTrace.log is appending and not rotating with size and number, even though the logger.properties files are updated.
Release : 12.8.06
you need to double check your LoggerConfig.properties and make sure the rollover set to 1 which is disabled
(LogRollover=1, LogSize=512, LogCount=10).
In order to enable log rollover you would need to configure LogRollover=4 and set the LogSize and LogCount accordingly.
The default is LogSize=10, LogCount=10, which would be 10 files of 10mb in size.
