I am not able to start elasticsearch. I tried
bin/elasticsearch
bin/elasticsearch -f
bin/elasticsearch -f ES_HEAP_SIZE=4g
but I keep getting the following message after a two-second pause...
{0.90.0}: Startup Failed ...
- OutOfMemoryError[unable to create new native thread]
NOTE 1: elasticsearch was working perfectly for me before I indexed 4 million documents into the server, after which I kept getting this error.
NOTE 2: even though elasticsearch does not startup, I am still able to execute the curl command on the elasticsearch server (strange indeed because elasticsearch is not running on the host machine - using ps command)
curl -XGET http://localhost:9200
{
"ok" : true,
"status" : 200,
"name" : "Thumbelina",
"version" : {
"number" : "0.90.0",
"snapshot_build" : false
},
"tagline" : "You Know, for Search"
}
My guess is that one of the search queries to the 4 million documents is still running but I tried exiting the terminal, killing the process, increasing the heap size and stopping the elasticsearch process using bin/elasticsearch stop. My elasticsearch version is 0.90.0. Sorry for the long question and any help would be great. Thanks.
