SYMFONY2 REDIS验证器，字符串而不是classMetadata

Question

我已经从memcach迁移到了redis。起初，我使用了PECL Redis 3.1.3，一切正常。更新为3.1.5后，我开始收到错误：

未接收的PHP例外 Symfony Component debug exception fatalthrowableerror："类型错误： 参数1传递给 Symfony Component Compention varter Mapping factory lazyloadingMetadataFactory :: MergeConstraints(((( 必须是 symfony component validator mapping classmetadata，字符串给定， 被称为 /var/www/acme/www/vendor/symfony/symfony/symfony/src/symfony/component/component/validator/mapping/factory/factory/lazyloadingmetavementafactory.php 在第95英寸 /var/www/acme/www/vendor/symfony/symfony/symfony/src/symfony/component/component/validator/mapping/factory/factory/lazyloadingmetavementafactory.php 第120行

我看了看，redis changelog，没有任何线索在两个版本更新后可能出了什么问题。

我的config.yml(仅缓存/redis东西(：

我的Symfony版本是2.8.31。有任何建议吗？

冲洗redis解决问题。

redis-cli flushall
