1. What would be the idle heap memory in production, we have 32 GB RAM
This is affected by MANY factors and would be impossible for us to predict.
A Tomcat with no applications deployed on it takes only a few MB of heap
space. Everything else will be your application.
2. Calling system very frequently see this error "Connect to
gte-onesource.wip.its.hpecorp.net:8080 failed: NIECONN_REFUSED(-10)", how
to fix this one?
That depends entirely on the reason the connections are being refused.
Follow Mark's recommendations for determining what the server is
actually doing when it becomes unresponsive. Only then would we be able
to suggest some action steps.
3. How to restart the server without impacting current transactions.
This depends upon how your transactions are structured. My guess is that
this is impossible unless you have made specific arrangements to allow
"transactions" (by whatever definition) to continue while Tomcat (really
your application) is not running.

Hello team,
Need your help to resolve the unresponsive behaviour of tomcat9 very
frequently which made us to restart the server to fix the issue which is
not a right thing.

Please let me know if you need any other details.
Next time it happens take 3 thread dumps each ~5 seconds apart. A 3-way
diff between those thread dumps is likely to show you where/why things
are backed up. If you need help interpreting that data, post the thread
dumps somewhere we can download them and send the links to this list.
