Bug Description

After upgrading our testing server to bionic, our web application stopped responding entirely
after the second request. We traced this to a problem in php-apcu where it would block upon the second
call to apcu_entry and completely lock up the php processes causing the server to become unresponsive to any further requests.

This issue was already reported and fixed upstream (release 5.1.11) and I have attached the diff for the corresponding commit, though I would like to note that there have been 3 bugfix releases since the packaged version (5.1.9).

Upstream issue: https://github.com/krakjoe/apcu/issues/246

Affected systems: anything running either php-fpm or apache with mod-php
