Description sch577 2013-05-16 17:25:20 UTC 
There is a problem with this file:

http://commons.wikimedia.org/wiki/File:ISS_Expedition_16_patch.png

It is within the new 50 MP limit, but thumbnails only get rendered till 270 px. Beyond the server says "Error generating thumbnail Error creating thumbnail:" without a clear notification.
The threshold seems to be wavering, maybe dependent server load and original file size.

Most likely an OOM
Comment 2 Bawolff (Brian Wolff) 2013-05-16 17:40:29 UTC 
Should this be duped to bug 47311 (or some other deploy vips bug)
