Need help locking the memory. I followed the instructions provided by Elasticsearch for my version to a “T,” however I on Linux nodes I get the dreaded “memory locking requested but memory not locked.” I have had to revert a snapshot to save the cluster so config files related to this don’t exist any longer; save the defaults in Elasticsearch.yml. I can repeat if necessary; but I’m hoping someone else has encountered this issue. Please advise.
