When I go to the actual thumbnail, after a long period of time, I eventually get a 503.

Which is kind of odd, as normally I would expect the shell command to timeout before it go to the point where varnish would 503.

Triaging as normal, but it looks like the thumbnails are generating now. Is this fixed?
