while(tokens.hasMoreTokens()){
listOfIPAddresses.add(tokens.nextToken());
}
Settings settings = Settings.settingsBuilder().put("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", 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()

Hello,

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