> @cserwen if we set the corresponding ack message timeout > 10s, that is longer than ck message timeout. Is this problem will be solved? BTW, i don't understand the adjust - 1500, do u know in which case it works? @lizhiboo 设置这个ack消息的超时时间超过10s，我不太明白这个怎么避免这个问题的发生:joy: 关于这个 - 1.5s的判断，在添加ack消息时会进行判断， 如果ack消息对应的ck消息在buffer中待的时间超过了`brokerController.getBrokerConfig().getPopCkStayBufferTime() - 1500`，这个时间，ack消息就必须写入延时Topic中，即这个时候ck消息不能被ack了，等reviveService去处理这部分ack消息。 我认为这1.5s应该是为了不想要加锁，提前禁止ck消息被ack？ -- This is an automated message from the Apache Git Service.
