[Mediawiki-l] Thumbnail generating problem with large PNG files

Fri Dec 16 06:08:16 UTC 2011

We have a problem with generating thumbnails for large PNG files (10300 
x 6000 and so on) in our intranet installation of MW 1.17.0. I've got a 
"Error creating thumbnail: Invalid thumbnail parameters" error.

Generation of JPG thumbs for big files works fine, generation of medium 
PNG files (2550 x 3510) works well too.

$wgMaxShellMemory and $wgMaxShellFileSize are set to "unlimited".

How can we find a bottleneck?
