In case it disappears later, here's the error message:

Error message generated does not contain any useful information.

That's bug 47571.

Might be a dup of bug 47534.

Sounds like a dupe to me.

this is an out of memory error since its a rather complex composition, one
option might be to increase the memory on the apache nodes.

Just as a note, on my local install, the example renders fine with $wgMaxShellMemory = 55000; which is about half the memory limit used by wmf.

Hmm, I close as a dupe, and then keep commenting on it, that's pretty bad practise.

Anyhow, just wanted to say I think you're right about it being a resource limit issue, not sure what the deal is with my local test not using that much resources...
