Deploying or migrating clients when using multi-byte character group names in the Symantec Endpoint Protection Management console
Symptom: If you create groups with names that use a double-byte character set, you cannot add new RU6 clients to those groups through any form of installation. New clients are automatically placed into the Default group.
Solution: With RU6, clients were incorrectly parsing DBCS characters resulting in a corrupt group name. When registering with the Symantec Endpoint Protection Manager using a corrupt group name, clients are placed into the Default group. With this fix, client-side changes were made to correctly parse DBCS group names.

Removal of periodic CPU spike when using Symantec Endpoint Protection Manager Java console
Symptom: With RU6, A periodic CPU spike occurs when a user selected the Policies, Clients, or Admin page in the Symantec Endpoint Protection Manager Java-based console.
Solution: This issue was caused by a periodic refresh of the Home page to prevent a time-out of the PHP session. The refresh task now refreshes the Reports page, which consumes fewer resources. In addition, you can now configure the refresh time by setting the scm.keepalivescheduleminute value in the conf.properties file.
The version number of the new build will be 11.0.6005.562 and will be labelled Symantec_Endpoint_Protection_11.0.6A_Xplat_EN_DVD.zip
