HTTP Web Server: HCL Notes Exception - This database is currently in use by another person

You get an error message when editing or saving a page.

HTTP Web Server: HCL Notes Exception - This database is currently in use by another person or process, and cannot be accessed at this time. In order to share a Notes database, it must be accessed via a Domino Server by all users of the database

Please let us know about this error using feedback. 

I will try and restart the server ASAP.

This is caused by the back up system by AWS .
