I'm using ES 5.2 on ubuntu 14.04

My yml contains:

**network.host: 0.0.0.0**  
**http.port: 9200**  
**transport.tcp.port: 9300**  
**transport.host: 0.0.0.0**  
**transport.bind\_host: 0.0.0.0**  
**transport.publish\_host: 0.0.0.0**

From the log the publish\_address is the correct one: 10.3.1.50:9300,  
but the bound\_addressed is wrong: [::]:9300, **I need it to be 0.0.0.0:9300**.

Here is the log:  
**initializing ...**

(\* the "max file descriptors" Error is not the reason because that with other yml the service is find)

Any ideas ?

Thanks

Hi @idanhagai,

This is being caused by bootstrap test failure. The bootstrap checks are run when ES detects that it is in "production mode", as opposed to "development mode".

In this case, attempting to bind to 0.0.0.0 triggered ES to run in production mode.  
Take a look at [this page](https://www.elastic.co/guide/en/elasticsearch/guide/master/deploy.html) that tells how to put ES in production mode.

See [here](https://www.elastic.co/guide/en/elasticsearch/reference/master/file-descriptors.html) for info about setting the max file descriptors

THANKS !!!

I increased the file description to 65536 and problem solved 😅
