This is typically occurring after an import and is due to the users being notified by a change not existing, causing a NullPointerException and a transaction rollback.
In OnDemand, it is reportedly caused by a deletion of user through JIRA OnDemand, which triggers deletion of the user in Confluence OnDemand. In Confluence watch list, this user is listed as undefined ().
We have seen this occur for page saves, page moves, page deletion and comment saving.
The stack trace is typically like this -
java.lang.NullPointerException

Workaround
As a space administrator, remove the invalid user from the watchers list. See screenshot:
This workaround doesn't work for me every time, the deleted watcher will disappear then reappear if I refresh the page. Here's the database queries to take care of it:
select username from user_mapping where user_key in (select username from notifications where contentid = <YOURPAGEIDHERE>); Hit edit on the page to get this, alternatively if the deleted user is watching the entire space sub the last part for spaceid = <YOURSPACEIDHERE>
With that statement pulled up you can compare to the watchers list on the page. Find the one that's in the SQL but not on the page, that's your culprit.
select user_key from user_mapping where username = '<YOURUSERNAMEHERE>'; ** This is the culprit username that doesn't match
If you haven't already make a backup of your connie DB
delete from notifications where username = '<YOURUSERKEYHERE>'; ** The user key from the above statement
This will also fix the problem for any other pages not that has that deleted user as a watcher
