Adobe InDesign sometimes crashes when saving a file to a Gluster volume over Samba

Issue

On seemingly random occasions, when a Windows client is saving a file to the storage server, the application will crash with an error:

The network connection was lost for the file filename.ext, or the file was modified by another process

Error logged in /var/log/glusterfs/gluster-data.log is:
