lushilin opened a new issue #3407: URL: https://github.com/apache/rocketmq/issues/3407
线上环境使用rocketmq的时候，发现一个场景，在用户大量新建consumerGroup上线的时候，会触发大量的%RETRY% topic自动创建，目前自动创建之后，broker会全量上报topic元数据到namesrv中，如果集群的topic很多，broker数量也很多，那么就会造成很多broker同时对namesrv发起全量topic meta的注册，会导致namesrv fullgc，造成namesrv雪崩。[](url) -- This is an automated message from the Apache Git Service.
