A few months ago, we upgraded the intranet of our company from Symfony 2.3 to Symfony 2.8 and from PHP 5.6 to 7.0.10. Then, we encountered a lot of "Fatal Errors" due to circular references that could be "erased" by restarting Wampserver. I read that this could be because of passing some parameters to services. I corrected this by passing and setting as property only the container, even if I'm not convinced that this is a good practice. I also read that it could be because of opcache, so I disabled this.
After that, we no longer have this problem. However, since two weeks a new "Fatal error" appears randomly :
PHP Fatal error: Class Symfony\Component\HttpFoundation\Session\Storage\Proxy\SessionHandlerProxy contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (SessionHandlerInterface::open) in C:\wamp\www\symfony\app\cache\prod\classes.php on line 393
or
PHP Fatal error: Class Symfony\Component\HttpFoundation\Session\Storage\Proxy\SessionHandlerProxy contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (SessionHandlerInterface::read) in C:\wamp\www\symfony\app\cache\prod\classes.php on line 393
We just restart the server and it works. I saw that many people had a similar error, but I could not find any real solution. I don't know if it's a PHP error or if it's due to a Symfony 2.8 - PHP7 incompatibility, despite Symfony achieves 100% PHP7 compatibility or if it's an error in our code.
I will try to know if this error appear after a specific action on the intranet.
I hope my problem is a little different and someone will find a solution. If I forgot something or if you want to see another part of code say me !

EDIT :
The issue has just been reproduced, I saw it when I opened the intranet so I don't know if it crashed before or when I opened it. There are no logs in the prod.log of Symfony but, in php_error.log of wamp, there are two errors :
