    <p>This sounds like it could be a file lock issue. NFS can lock files being executed/accessed while they prevent others from accessing them. Implemented in bad fashions it can lead to a deadlock which results in the file being useless until the application accessing it is removed.</p> <p>Here is some more information on File Locking: <a href="http://en.wikipedia.org/wiki/File_locking" rel="nofollow">http://en.wikipedia.org/wiki/File_locking</a></p> <p>I would recommend checking to see how your NFS is configured in regards to File Locking and address that against your needs for accessing it. </p> <p>If it is read only, you don't really need to have file locking enabled as the primary benefits of File locking are to prevent two people from writing to a location at the same time or when someone is writing to a location, preventing someone from reading an outdated or not completely finished version of the data. As a read only data point this is not required in this situation.</p> <p><strong>Update:</strong></p> <p>To disable File Locking on Linux NFS, when you mount the NFS point, in the options you assign to it, add nolock.</p> <p>For example if this was your /etc/fstab:</p> <pre><code>/dev/hda2 / ext2 defaults 1 1 /dev/hdb1 /home ext2 defaults 1 2 /dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0 /dev/fd0 /media/floppy auto rw,noauto,user,sync 0 0 proc /proc proc defaults 0 0 /dev/hda1 swap swap pri=42 0 0 nfssrv.server.com:/content /opt/content nfs rw,bg,soft,actimeo=0,rsize=8192 0 0 </code></pre> <p>You would change it to:</p> <pre><code>/dev/hda2 / ext2 defaults 1 1 /dev/hdb1 /home ext2 defaults 1 2 /dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0 /dev/fd0 /media/floppy auto rw,noauto,user,sync 0 0 proc /proc proc defaults 0 0 /dev/hda1 swap swap pri=42 0 0 nfssrv.server.com:/content /opt/content nfs rw,bg,soft,actimeo=0,rsize=8192,nolock 0 0 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
