[1]: memory locking requested for elasticsearch process but memory is not locked
Did you follow the guide here? Memory lock check | Elasticsearch Guide [8.11] | Elastic
I saw that comment on the guide: Disable swapping | Elasticsearch Guide [8.11] | Elastic
mlockall might cause the JVM or shell session to exit if it tries to allocate more memory than is available!
May be this is what is happening here?
