The drive where the DLO application is installed, runs out of space, causing the 'Mindtree StoreSmart Dedupe Server' service to crash.
NOTE: This issue is resolved in DLO 9.4. These settings are automatically updated during DLO 9.4 upgrade.
Ways to help reduce the amount of space being used by DLO\Dedupe logs are given below:

1. Go to "..\Program Files\Veritas\Veritas DLO\Dedupe\Tomcat\conf\"
2. Look for 'logging.properties' file
3. Create a backup of the file --> Copy the file to same folder and rename it to 'logging.properties.BAK'
3. Edit 'logging.properties' file
4. Look for following line:
.handlers = 1catalina.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler
.. and replace with
.handlers = 1catalina.org.apache.juli.FileHandler
5. Save 'logging.properties' file.
6. Restart the 'Mindtree StoreSmart Dedupe Server' service, to read that new logging settings.
