We were able to find what the problem is
We are able to reproduce the issue only when
• he content item is programmatically edited or created.
• you use View_Could
metakey of the Blogs Provider. When someone views an item from the public side where you have BlogPosts control the item gets locked by unknown user and View_Count value is updated.
In both cases
• context.User.Identity.Name from the current context is String.Empty or Null - in this case the user is not logged in.
• IPrincipal is null, principal.Identity.Name is null or String.Empty - the user is not logged in.
To fix the problem is to comment the following line from your web.config in case you do not use View_Count in some implementation.
The problem fix will come with the next SP. In case you use this metakey and you cannot comment it, please open a support request.
