Sometime I see this kind of error in my logs: apache error logs: Got error 'PHP message: PHP Notice: apcu_fetch(): Error at offset 0 of 426 bytes in .../vendor/symfony/symfony/src/Symfony/Component/Cache/Adapter/ApcuAdapter.php on line 53 Followed by a symfony log Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalThrowableError: "Call to a member function getLength() on null" at .../vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php line 194 Once this problem occured theses errors are repeated until the apcu cache is cleared (which can take hours). As this problem occured randomly, I can not repeat it when I want. Serveur Debian 9 / apache 2.4.25 with php-fpm / PHP 7.0.27 / apcu 5.1.3

The issue is in the Cache component to me. isHit should return false when this happens in the first place. So 👎 for the patch as it is, but definitely 👍 for the report, thanks for it. We now need to figure out a proper way to fix the issue in Cache. |
