ES Version: 6.3.0
There are too many same logs like this, I have seen others said that this is a BUG?

This isn't a direct answer sorry, but it's important;

That version is [EOL](https://www.elastic.co/support/eol) and no longer supported, you should be looking to upgrade as a matter of urgency.

It was released nearly [5 years ago](https://www.elastic.co/blog/elasticsearch-6-3-0-released)! A lot of these sorts of issues are resolved with upgrading and given you are running an unsupported version you will get that answer a lot sorry to say.
