Uncertain Error Occurs in Symfony

Question

I am doing my project in symfony.

Sometimes when my pages load i got below error :

Fatal error: Class Symfony\Component\HttpFoundation\Session\Storage\Proxy\SessionHandlerProxy contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (SessionHandlerInterface::close, SessionHandlerInterface::gc) in D:\xampp\htdocs\meopin_mobile2\trunk\var\cache\prod\classes.php on line 348

Do anybody have any idea about this error , how can i stop this ?

Thanks in Advance

Try to clear the caches with a command php bin/console cache:clear --no-warmup --env=prod
