It seems, that despite the settings being configured, they are not applied properly. Either you may need to relogin (not sure how you start Elasticsearch) or your operating system has another mechanism of setting these and may potentially overwrite or ignore your configuration. See [https://www.elastic.co/guide/en/elasticsearch/reference/6.5/setup-configuration-memory.html#bootstrap-memory\_lock](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/setup-configuration-memory.html#bootstrap-memory_lock) for more configuration options and [https://www.elastic.co/guide/en/elasticsearch/reference/6.5/file-descriptors.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/file-descriptors.html) for more infos about file descriptors. --Alex ---
