For Symantec Endpoint protection manager\inetpub, follow the steps below to adjust the number of content updates stored by Symantec Protection Center:
- Open the \Program Files\Symantec\Symantec Endpoint Protection Manager\tomcat\etc\conf.properties file.
- Add the following setting to the file, (the example uses a value of 5, adjust the value as necessary, the default value is 10 if no entry is present) scm.lucontentcleanup.threshold=5
- Close the conf.properties file and click Yes to save your changes.
- Click Start > Run.
- Type services.msc and click OK.
- Right-click on Symantec Endpoint Protection Manager, and click Restart.
