Hi Team,
I am using ElasticSearch 7.6.2, sometimes when we request query I am getting OOM (Out Of Memory) may I know how to tackle this issue?
Hardware environment as follows:
Server capacity
vCPUs: 8
RAM: 32GB
Storage: 100GB
ES Health
"cluster_name" : "elasticsearch",
"status" : "yellow",
"timed_out" : false,

memory allocated to ES is 20GB, but still getting OOM error sometimes, need to Restart ES every time.
