Thank You Andre so much
will check the below now
quick fix, without guarantee :
in your setenv.sh file, just replace
JAVA_OPTS=..
by
CATALINA_OPTS=..
and you will probably be ok.

Actually, I think that you need to look closer at the tomcat shutdown
scripts on your
system, and their settings.
If I remember correctly, when you call the tomcat shutdown script, it
actually starts
another java JVM instance, just to send a shutdown message to the running
tomcat's JVM.
And with your current JAVA_OPTS, it looks like this shutdown JVM is also
requesting a Java
heap with an initial size of 8 GB. And that is what may trigger this OOM.
There is something in that area about the difference between JAVA_OPTS and
CATALINA_OPTS.
Additional information :
(I have now found it again)
Somewhere in your tomcat software directory (which may be anywhere,
depending on where you got this tomcat from), there is a file named
"RUNNING.txt".
In this file is a section which I copy below here, in case you are having
trouble finding it. It explains what happens with these JAVA_OPTS and
CATALINA_OPTS environment variables. In particular the last paragraph.
quote
...
(3.3) Other variables (optional)
Other environment variables exist, besides the four described above.
See the comments at the top of catalina.bat or catalina.sh scripts for
the list and a description of each of them.
One frequently used variable is CATALINA_OPTS. It allows specification of
additional options for the java command that starts Tomcat.
See the Java documentation for the options that affect the Java Runtime
Environment.
See the "System Properties" page in the Tomcat Configuration Reference for
the system properties that are specific to Tomcat.
A similar variable is JAVA_OPTS. It is used less frequently. It allows
specification of options that are used both to start and to stop Tomcat as
well
as for other commands.
Note: Do not use JAVA_OPTS to specify memory limits. You do not need much
memory for a small process that is used to stop Tomcat. Those settings
belong to CATALINA_OPTS.

Hmm, that's a nice logfile.
It also starts with a number of hints and recommendations, did you see ?
Very generically :
When tomcat is shutting down, it does need some extra memory for a while,
to run the
shutdown processes (in addition to the other processes which are
running).
So it asks the Java JVM for more memory.
And then the java JVM asks the OS for that extra memory.
And in your case, it does not get it, because the OS is telling it that
there is no more
available memory. So the JVM crashes.
Now why there is no more memory available at that time, is mostly for you
to find out.
There are certainly other processes running on that server, in addition
to tomcat's java
JVM. They use memory too.
And otherwise, either you need a bigger system, or you need smaller
applications.

Well no. Only the "setenv.sh" was attached.
This list server strips many attachments. Maybe you need to paste the
content directly into your message (if not too long), or post it
somewhere
where we can look at it.

And does the above-mentioned error report file contain more
