Is there a typo in there - from what you write below it looks like you want to start multiple nodes on a single _server_?

Without knowing what exactly you did it's hard to guess what went wrong.

If you are indeed trying to run multiple ES nodes on one server the following instructions might help you:

But we do have a few customers with big machines (eg. 512 RAM, 256 cores, etc..) who have deployed multiple Elasticsearch nodes per big machine. There are some caveats and recommendations if you choose this deployment architecture: Max heap size for each node instance should be \< 32Gb. This is because a heap size above 32Gb will actually be counterproductive for the JVM will stop compressing pointers ([https://wikis…](https://wikis.oracle.com/display/HotSpotInternals/CompressedOops)

Hope this helps,
