Thank you Aaron and Bryan for your advice.
I have changed following parameters and now Cassandra running absolutely fine. Please review below setting and advice am I right or right direction.
# do not persist caches to disk
I have a querry, if Cassandra is using JVM for all operations then why we need change above parameters separately in cassandra.yaml.
Thanks & Regards

We can see from below that you've tweaked and disabled many of the memory "safety valve" and other memory related settings.Agree.
Also you are running with JVM heap size of 3.81GB which is non default. For a 16GB node I would expect 8GB.
Try restoring the yaml values to the defaults and allowing the cassandra-env.sh file to determine the memory size.
