Tomcat9 service outage takes more than a minute

We need to investigate why it's late.

First, check the Tomcat logs (logs/catalina.out) to see if there are any messages that might be relevant during a service outage.If you can't determine the cause (although it's unlikely) then try to retrieve the thread dump multiple times during the service outage process.

The thread dump shows stack traces of multiple threads, so please check if there are any possible causes of the delay.We expect that there will probably be some thread left on the deployed application.If you don't understand, please add a thread dump to the body of the question.
