Symptoms:

• Array Manager log error: Failed to load policy: System.Exception: Failed to open filtering list DLL.
• Node Controller log error: Failed to load filtering list DLL "MCMarshal.dll".

• As noted in the Release Notes, these filtering lists are not supported and cannot be licensed. They must be removed from configuration before upgrade.
• The linking DLLs have been removed in version 7.X
• Some customers with expired trials of these filtering lists may have been unaware that they were still present in the list of URL filtering lists.

Resolution:

To resolve this issue after upgrading, it is necessary to manually edit the WebMarshal configuration file.
