Tomcat not stopped due to Alfesco webapp 201911 GA (6.2)

Hi Team, 

I am not able to stop the tomcat instance using shutdown.sh. The process is still running and getting the following  like warning and errors in log,

06-Jan-2020 04:28:27.812 WARNING [localhost-startStop-2] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [alfresco] appears to have started a thread named [Timer-0] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:
java.base@11.0.5/java.lang.Object.wait(Native Method)
java.base@11.0.5/java.util.TimerThread.mainLoop(Timer.java:553)

Threads are going to be renewed over time to try and avoid a probable memory leak

Re: Tomcat not stopped due to Alfesco webapp 201911 GA (6.2)

Thanks for the response, I have reviewed the mentioned post but haven't found the solution. 

My issue is tomcat is stopped (while checking the ports), but the process is not killed, 

The web app threads do not stop properly. 

Thanks

I do not see any open bugs on this with this version of community. I have been researching. I did find something that someone wrote to assist with Tomcat shutdown. I don't know if it may help: https://github.com/wabson/build-tomcat-bundles/blob/master/bundle-files/linux/alfresco.sh
