vCAC Appliance and ID admin consoles throwing java errors

Since upgrading to from 6.0.1 to 6.1 (and oh what a joyful experience that was) I now have the following error messages appearing on the vCAC and ID appliances admin pages:-

vCAC Appliance > Admin :-

     Invalid request(getValues), action(query) or missing controller(<__main__.Controller instance at 0xab95a8>

ID Appliance > Admin:-

     Invalid request(getValues), action(query) or missing controller(<__main__.Controller instance at 0xab75a8>)

ID Appliance > SSO > Logs:-

     Invalid request(logInfo), action(query) or missing controller(<__main__.Controller instance at 0xaa5ab8>)

These errors don't appear to be critical so its no big deal but any ideas on how to clear these?

Cheers

Danny
