SpringBoot After executing "kill-15<pid>", my app encountered an exception during the shutdown process Failed to stop bean 'webServerGracefulShutdown'

Environment

spring-boot 2.3.4.RELEASE
ubuntu 16.04.1 4.15.0 x86_64

Background

After executing the kill -15 <pid> command, my spring-boot application has error log Failed to stop bean 'webServerGracefulShutdown' during the shutdown process.

and the error cause by shutdown process lasted for 1 minute. In normal, I think it only takes a few seconds to complete graceful shutdown.

Could you kindly please help me to resolve the exception?
