Multiple PDFs not accessible

Cannot download this document from this response.

Also can't access this document from this response.

This issue started happening at the same time we received alerts about the cron jobs stalling. Unsure if it's related?

With the first document I went into the admin console and downloaded the "raw" eml file. When I opened that (in Thunderbird) I could look at the pdf so the raw email data is okay.

Allright I've fiddled around with all the cache setup and I can't make it do anything different. However the problem only occurs on a small number of files so I'm guessing there's something in the PDF that's making things go wrong. Also, if you try to download the document the cpu gets pegged at 100% and the server will likely die. So, avoid if possible...

I'm going to take a break from this problem for a little bit and come back to it. Hopefully something will jump out to try soon.

@mlandauer not sure if this is (possibly) relevant, but we use a slightly out-of-date version of wkhtmltopdf (0.12.5)
