I am using Libre Office wordprocessor on Kubuntu 13.04. My data is stored on a NAS (Synology DS213+) and accesses using NFS.
When trying to access files from the NAS, LibreOffice locks up and freezes. There are no problems with any other programs accessing data (including Email etc) . Copying a file to the local computer allows it to be opened OK by LibreOffice, so it appears to be a problem with LibreOffice and networking.
that sounds very much like an NFS locking problem. Libre Office is trying to lock the file so it has exclusive Write access to it while it's open.
FWIW, these symptoms also present with people using MS Office + Outlook and samba3. My strong impression is that locking just doesn't work very well under ANY network filesystem. IIRC my approach for samba3 is the equivalent to export-with-nolock, which causes the clients to do client- side locking, at a small[0] performance penalty. [0] smb.conf says "up to 30%" IIRC, but I never heard anybody complain after I made the change.
