What are the different kind of OutOfMemory in ElasticSearch?

Hi Team,

What are the different cases where OutOfMemory might occur?
I want to test my ES cluster with OutOfMemory exceptions. I would like to explore the options to obtain the same.
What settings would help me create the exceptions?

Thanks
