This issue happens intermittently on FPM servers and Symfony's caching functionality is the only place where I've seen it occur. Unfortunately, it's just something that I've seen in logs; I don't have a quick script that simply reproduces the issue. I added the Symfony bug on GitHub (which was closed due to it being a bug in PHP, not Symfony) to this ticket's "Affects" section, above.
