Since it has been up to 39 months since the quoted users have submitted a post on this topic, I believe that it is necessary to ask for an update: has anyone experienced any problems as a result of disabling file lock? The admin is making a cautious decision regarding the file lock configuration on an installation with one user on Notes, Calendar, and Deck at a time. Please provide the version numbers in your reply to provide readers a more informed decision.
If I remember right, that error is caused by a locked file. Take a look at the following URL, under " Manually disable locking state ".
