ShutdownHookMQTrace causes the process to fail to exit quickly when the consumer shutdown

I'm using the client version 4.9.3, and I've added message trace for both producer and consumer

I added shutdownhook to the project to complete the graceful exit of the project, which includes producer and consumer stops. However, the process cannot exit quickly during execution. The maximum duration is one minute. The stack information shows that the thread is blocked for a long time, causing the process to exit after about a minute.

How can I quickly shut down the MQ client

According to the stack information, it is assumed that the long-running thread blocked where the size of ArrayBlockingQueue was gotten in the flush() method when traceDispatcher shutdown. Here's the partial stack information I got.

Hi 曾雪薇,

Could you please provide a flame graph or more information about the shutdown process? I didn't see any connection between this issue and the message trace based on your description.


Your response would be highly appreciated.
