BurningCN opened a new issue, #4451:
URL: https://github.com/apache/rocketmq/issues/4451

   
   Because the `put` operation occurs after the `lock`, and the `lock` method 
will not be able to obtain the `processQueue` and `setLocked(true)`
   So it can only be locked by timed tasks (`lockMQPeriodically`)
