Perform an upgrade restart on the ProxySG appliance. A normal restart does not help in clearing the corruption issue but an upgrade would help because an upgrade always performs some sort of policy migration. This will help
in clearing any corruption.
If you do not want to or cannot upgrade, the alternative is to do a restore factory defaults. This will delete all files on the ProxySG appliance except IP data needed to access the console. Listable files, including policy files, will
be deleted. Theoretically, this action should also clear this type of corruption. For instructions, refer to article 000011251 or the Command Line Interface Reference for the SGOS version you are using.
