Graceful Shutdown As of Spring Boot 2.3, Spring Boot now supports the graceful shutdown feature for all four embedded web servers (Tomcat, Jetty, Undertow, and Netty) on both servlet and reactive platforms. Essentially,it blocks the JVM shutdown to wait for the Tomcat to be finished with pending requests. The WINCH or graceful-stop signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). Docker will kill the container after 10 seconds. As you can see, Redis is running as PID 6, which is why graceful stop doesn't work. If you check container logs docker logs test, the last message will be Ready to accept connections, meaning Redis didn't receive termination signal. The reason for this is that if you have too many badly behaved threads then typing Tomcat's shutdown.sh command will have very little effect and you have to savagely kill your web server by typing something like: ps -ef | grep java to get the pid and then kill -9 <> If the timeout is reached, any rem… Introduction A lot … This is the class and the way the application registers itself with the ELB.

Once all children have finalised and exited or the timeout specified by the GracefulShutdownTimeout has been reached, the parent will also exit. Let’s try to stop this container with a docker stop test. Note: Disabling the shutdown port works well when Tomcat is started using Apache Commons Daemon (running as a service on Windows or with jsvc on un*xes). It cannot be used when running Tomcat with the standard shell scripts though, as it will prevent shutdown.bat|.sh and catalina.bat|.sh from stopping it gracefully. Hi, Using 657 build with Tomcat 4.0.6 (LE edition for jdk 1.4), everything works fine so far but I noticed when I stop running tomcat it actually terminates the process instead of proper shutdown.
