Elasticsearch throws Could not reserve enough space for object heap

Elastic Stack Elasticsearch
1

Hi guys,

It seems that Elasticsearch stops working this morning.
When i launch : sudo service elasticsearch start, it says : Starting
ElasticSearch Server Done

But when i check the status, it gives me : elasticsearch is not running

I tried to launch it by the command :
/usr/share/elasticsearch/bin/elasticsearch start
it gives me :

Error occurred during initialization of VM Could not reserve enough space
for object heap

I tried to set 512m for Heap size in :
/usr/share/elasticsearch/bin/service/elasticsearch.conf

set.default.ES_HOME=
set.default.ES_HEAP_SIZE=512

But it didn't work.
How could i fix that?

What happen if you try 512m instead of 512

Do you have already some indexed data?
If so, may be 512m is not enough. It's a really low value.

Yes, Elasticsearch was deployed on the Vps 3 months ago, it worked
perfectly, until today.

VPS config : 512MB Ram, 20GB SSD Disk

Best practise is to use half of system ram for your heap, so ideally you
should be setting it to 256mb.
However you probably want to add more system RAM as you're hitting the
limits with what you have.

I tried low sizes : 256 and 128, it does not work.

The vps is only used to host Ruby on rails Api for mobile apps
(Ruby, Postgresql, Redis...)

It can not work with less RAM.
May be starting new nodes to have less shards per node could help but I'm guessing you don't want to do that.
