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? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

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.
