Hello,

I'm trying to start my Elasticsearch servcie on RHEL Environment but I'm unable to start it after N days of not monitoring it. With this, I'm unable to access the Kibana dashboard.

You should check this - [System call filter check | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/_system_call_filter_check.html)

Hi @warkolm thank you for sharing the reference. However, upon checking even though its not recommended, I've tried to set the `bootstrap.system_call_filter: false` but elasticsearch cannot be started. To give you a brief background, the elasticsearch has been working for N months. Is it possible that it was affected by the upgrades in the environment if there's any?

I was able to resolve the issue by temporary disabling the `bootstrap.system_call_filter` on elasticsearch.yml. After that I've tried to start and look at the logs again and resolve the new error by following this steps.
