Elastisearch conf is
1 node :
bootstrap.memory_lock: true
thread_pool.index.queue_size: 1000
xpack.ml.enabled: false
action.auto_create_index: true
xpack.monitoring.enabled: false
xpack.security.enabled: false

any tips ? thanks

How many indices and shards do you have on the node now?

Why have you overridden this if you are running in an environment with limited memory?
