I am having a problem changing page permissions (adding a role to a page)

When I attempt to change permissions on a page, it seems the process is only starting but not completing.

The admin page comes back with an unknown error (logged in as Admin).

(Logged in as user with role on another browser) The page now shows up in the Menu but when trying to access the page I get: "You do not have access to view this page within the website"

(Browser with admin) shows that the role was not added to the page.

From event viewer:

I can edit a pages content but the callback doesn't seem to complete correctly

Any help would be appreciated.
