plz help me

Hi @abdul ,

It will be easier to help if you also share your configuration.

Could you also update on the following

[opensearch-cluster-master-0] bound or publishing to a non-loopback address, enforcing bootstrap checksERROR: [1] bootstrap checks failed[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]ERROR: OpenSearch did not exit normally - check the logs at /usr/share/opensearch/logs/opensearch-cluster.log

It is asking you to update the limit for vm.max_map_count - Can you do this and try again. You can find more here - Installing OpenSearch - OpenSearch Documentation

Leeroy.

@Leeroy According to you, vm.max_map_count=262144 is set, and now it is showing this error.
