Hi all,
Ever since my recent upgrades to MediaWiki 1.27, which included upgrading the operating system and changing from Apache + mod_php to Apache + PHP-FPM, a few times I've seen PHP-FPM processes hanging on a certain kind of old page revision (often these revisions are years old). Specifically, it appears to be old page revisions where there was a huge change to the page size, e.g. a 64k page having 61k added to it. Here's an example excerpt from the FPM status page with the pool info and one of the hung processes:
Do you have the wikidiff2 PHP extension[1] installed? If you're having performance problems with diffs, switching to the C-based implementation should help. Diffs of that size are going to be large regardless, so I'm not too surprised it's having issues...
I'm not familiar with php-fpm timeouts to give advice on that, sorry.
