Hi Sergiy,

I have asked my network administrator to do this at next restart.

In the meantime, are you familiar with the container duplication, or is
this a likely cause of this occurring?

Regards,

Paul

Hello Paul,

could you please when you will shut down the server the server next time

create a JVM heap dump in order to provide us more information on what 
exectly is preventing it from shutting down properly?
On a Unix based systems your can issue the:
kill -QUIT <pid>
command. Where <pid> is the ID of your Java process.
The dump will be written into server log file or catalina.out

On Windows system the heap dump is created by pressing CRTL+Break in the

server console. The output will be written into the console.

Both Unix and Windows variants are not shutting down or interrupting the

server. It is safe to execute this command.

Kind regards
Sergiy

P.S. I am attaching an example of the heap dump as dump.txt
