I am using elasticsearch 5.6.1 with Fess. Unfortunately my server ran out of memory. After restarting the server and running Elasticsearch realized that the main index is closed. First tried to re-open it but no success. Also have tried to repair it but no success at all. I am new to Elasticsearch and don't know what to do next to recover all my indexed data. How can I prevent to run into out of memory?

Hello @PakanAngel

can you paste here part of the elasticsearch log and also the \_cluster / health output?

**Thanks Fram.**

**This is what I get when trying to recover the corrupted index.**

[root@localhost elasticsearch]# curl 'localhost:9200/fess.20171224/\_index/health/?pretty'  
{  
"error" : {  
"root\_cause" : [  
{  
"type" : "index\_closed\_exception",  
"reason" : "closed",  
"index\_uuid" : "9WUbb1GfQJChHc6l9mkuBw",  
"index" : "fess.20171224"  
}  
],

"index" : "fess.20171224"  
},  
"status" : 403  
}

**This is part of the elasticsearch.log file.**

That's a very weird problem there. I think @Adrien_Grand will find this interesting.
