baihezhuo commented on issue #1585: RMQ 4.2.0 - 4.5.2 [TIMEOUT_CLEAN_QUEUE] URL: https://github.com/apache/rocketmq/issues/1585#issuecomment-552731659 > > > 可以看看日志是不是主从连接有断开的情况，在tps比较小的场景可能会触发主从连接断开，将会导致这个问题，将master的haSendHeartbeatInterval修改成大于slave的值即可解决。可以参考这个#1082 我临时在看ha的代码，希望能从中找出解决问题的思路，目前来看在tps不高的情况下被流控，让我很困惑；压测环境的并发都是1000个线程起的；iops 达到3-4000都没任何问题。但是线上环境就经常被流控；
