I am getting a circuit breaker exception. I am trying to understand the error message.
- [123273216/117.5mb] - parent circuit breaker limit (95%).
- new bytes reserved [3666526/3.4mb] - this means the new request memory needs
- [123848638/118.1mb] - current heap + new bytes reserved
- real usage: [120182112/114.6mb] - current heap status
Is my understanding correct?

What heap size do you have configured?
Which version of Elasticsearch are you using?

I do not think I have ever seen Elasticsearch node run with successfully with a heap smaller than 512MB, especially for older versions like the one you are using, and that would generally only be suitable for a small test instance. I would recommend you increase the heap size to a minimum of 512MB.

ok. I want to understand the error. Is the below interpretation correct according to the error?
- [123273216/117.5mb] - parent circuit breaker limit (95%).
- new bytes reserved [3666526/3.4mb] - this means the new request memory needs
- [123848638/118.1mb] - current heap + new bytes reserved
- real usage: [120182112/114.6mb] - current heap status
