Hello, Experts.

I can't add network.host data or network.bind\_host.  
When I add below line, elasticsearch occur error.

How can I solve it?

This is my process,

**1. Add line in elasticsearch.yml**

> network.host: 0.0.0.0  
> or  
> network.bind\_host: 0.0.0.0

**2. restart elasticsearch**

> sudo -i service elasticsearch restart  
> or  
> /etc/init.d/elasticsearch restart

**3. status check**

> sudo -i service elasticsearch status  
> or  
> /etc/init.d/elasticsearch status

**4. Occur Error**  
elasticsearch dead but subsys locked

The logs will probably tell you something.

And I'm pretty sure it's related to Bootstrap checks. [https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html)

Thanks a lot.

I was checked 3 Bootstraps problems.

how to solve it?

> [3] bootstrap checks failed  
> [1]: **memory lock** ing requested for elasticsearch process but memory is not locked  
> [2]: max number of threads [1024] for user [elasticsearch] is too low, **increase to at least [4096]**  
> [3]: **system call filters failed to install** ; check the logs and fix your configuration or disable system call filters at your own risk

Pro.1  
I was set like this for [1]

> bootstrap.memory\_lock: true

already I set memory\_lock true

Pro.2  
I was check like this for [2]

> ulimit -u  
> 4096

already threads are over the 4096

Pro.3  
What am i need to check for ?

How to Solve these problems?
