Hi Everyone,

Iam tring to get data from the elasticsearch and also pushing data to eleasticsearch..But when i do continuesly ...I am getting below exceptions

Java Code side Exception:  
disconnecting...  
ReceiveTimeoutTransportException[[]

Elasticsearch logs:  
java.io.IOException: Too many open files

Here is my code

//GETTING RECORDS CODE  
StringTokenizer tokens = new StringTokenizer(ipAddress, ",");  
while(tokens.hasMoreTokens()){  
listOfIPAddresses.add(tokens.nextToken());   
}  
Settings settings = Settings.settingsBuilder().put("[cluster.name](http://cluster.name)",clusterName).build();  
for(int index = 0;index\<listOfIPAddresses.size();index++){  
transportClient = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress(listOfIPAddresses.get(index),Integer.parseInt(esPort))));   
}

```
		SearchRequestBuilder srb = transportClient.prepareSearch(indexName).setTypes(indexMapping)
	            .setSearchType(SearchType.DFS_QUERY_THEN_FETCH).addSort(SortBuilders.fieldSort(esTimeStamp).order(SortOrder.DESC));

```

queryDate = QueryBuilders.rangeQuery(esTimeStamp).to(todate).from(fromdate);

```
	    //addSort(SortBuilders.fieldSort("_id").order(SortOrder.DESC))
	    SearchResponse searchResponse =srb.setFrom(0).setSize(10000).execute().actionGet();

```

SearchHit[] searchResults = searchResponse.getHits().getHits();  
//Getting records code here

transportClient.close();

//pushing RECORDS code  
Settings settings = Settings.settingsBuilder().put("[cluster.name](http://cluster.name)", clusterName).build();  
for(int index = 0;index\<listOfIPAddresses.size();index++){  
transportClient = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress(listOfIPAddresses.get(index),Integer.parseInt(esPort))));

```
		       }
		response = transportClient.prepareIndex(indexName, indexMapping).setSource(jsonString).execute()
				.actionGet();

```

transportClient.close();

Please anyone Help me where iam going wrong....

Hello,

Can you try to increase these limits, like on [https://easyengine.io/tutorials/linux/increase-open-files-limit/](https://easyengine.io/tutorials/linux/increase-open-files-limit/) ?
