symfony 2.8生产环境 中的memcached错误

Question

奇怪的是，该错误仅在生产环境中发生。 apache error_log中的错误：

[Sat Dec 10 18:35:44.122028 2016] [proxy_fcgi:error] [pid 7916] [client 81.202.203.209:47076] AH01071: Got error 'PHP message: PHP Fatal error:  Uncaught exception 'Symfony\\Component\\DependencyInjection\\Exception\\ServiceNotFoundException' with message 'The service "doctrine.orm.default_entity_manager" has a dependency on a non-existent service "doctrine.cache.memcached".' in /var/www/vhosts/xxxx.com/xxxx/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/CheckExceptionOnInvalidReferenceBehaviorPass.php:58\nStack trace:\n#0 /var/www/vhosts/xxxx.com/xxxx/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/CheckExceptionOnInvalidReferenceBehaviorPass.php(51): Symfony\\Component\\DependencyInjection\\Compiler\\CheckExceptionOnInvalidReferenceBehaviorPass->processReferences(Array)\n#1 /var/www/vhosts/xxxx.com/xxxx/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/CheckExceptionOnInvalidReferenceBehaviorPass.php(51): Symfony\\Component\\DependencyInjection\\Compiler\\CheckExceptionOnInvalidReferenceBehaviorPass->processReferences(...\n', referer: xxxx

这是在生产环境中对我有用的配置：

parameters:
  ....
  memcache_hosts:
    -
        dsn: 127.0.0.1
        port: 11211
