Elasticsearch上的“打开文件太多”(“Too many open files” on Elasticsearch)

 我有一个集群ES，从2天前我有这个错误：  
[2016-03-14 15:08:48,342][WARN ][cluster.action.shard] [node-01] [logstash-2016.03.14][2] received shard failed for [logstash-2016.03.14][2], node[72oHnFiXTVqgXaUYKTAu2Q], [P], s[INITIALIZING], indexUUID [AKybrAEZRXebyRxcmzTqJQ], reason [Failed to start shard, message [IndexShardGatewayRecoveryException[[logstash-2016.03.14][2] failed recovery]; nested: EngineCreationFailureException[[logstash-2016.03.14][2] failed to open reader on writer]; nested: FileSystemException[/var/lib/elasticsearch/elasticsearch/nodes/0/indices/logstash-2016.03.14/2/index/_lg_Lucene410_0.dvm: Too many open files]; ]]
 
 如果我运行curl -XGET 'http://localhost:9200/_nodes?os=true&process=true&pretty=true' | grep "max_file_descriptors" curl -XGET 'http://localhost:9200/_nodes?os=true&process=true&pretty=true' | grep "max_file_descriptors"我有这个输出：  
"max_file_descriptors" : 65535,
"max_file_descriptors" : 65535,
 
 到文件/etc/security/limit.conf我已经有：  
elasticsearch - nofile 65535
elasticsearch - memlock unlimited
 
 如果我检查索引的状态我有一些索引RED ....因此logstash出错并崩溃所有 

i have a cluster ES and from 2 days ago i have this error: 
[2016-03-14 15:08:48,342][WARN ][cluster.action.shard] [node-01] [logstash-2016.03.14][2] received shard failed for [logstash-2016.03.14][2], node[72oHnFiXTVqgXaUYKTAu2Q], [P], s[INITIALIZING], indexUUID [AKybrAEZRXebyRxcmzTqJQ], reason [Failed to start shard, message [IndexShardGatewayRecoveryException[[logstash-2016.03.14][2] failed recovery]; nested: EngineCreationFailureException[[logstash-2016.03.14][2] failed to open reader on writer]; nested: FileSystemException[/var/lib/elasticsearch/elasticsearch/nodes/0/indices/logstash-2016.03.14/2/index/_lg_Lucene410_0.dvm: Too many open files]; ]]
 
If i run curl -XGET 'http://localhost:9200/_nodes?os=true&process=true&pretty=true' | grep "max_file_descriptors" i have this output: 
"max_file_descriptors" : 65535,
"max_file_descriptors" : 65535,
 
To the file /etc/security/limit.conf i already have: 
elasticsearch - nofile 65535
elasticsearch - memlock unlimited
 
If i check the status of index i have some index RED....consequently logstash goes wrong and crashes all

  垂直或水平绘制并添加0.5（jsfiddle.net/xr5az/2/） - 您将只获得黑白颜色。 （注意我隐藏线的开头和结尾，它会是灰色的...） 
 ctx.moveTo（-2,5.5）; ctx.lineTo（17,5.5）; ctx.stroke（）;  
  当你添加角度时，系统会添加额外的灰色像素，没有它，线看起来会很糟糕。  
  如果您只想从黑色获取线条，请在线条起点和终点之间绘制许多单独的像素（如果想要线宽> 1则绘制正方形）。  
 
 ps对不起破碎的小提琴链接，系统踢了我的消息，即使代码包括10次...... 

 
 draw vertically or horizontally and add 0.5 (jsfiddle.net/xr5az/2/) - you will get only black and white colours. (note that i hided line begin and end, it would be grey ...)
 ctx.moveTo(-2, 5.5); ctx.lineTo(17, 5.5); ctx.stroke(); 
 when you add angle, system adds extra grey colors pixels, without it, line would look bad. 
 if you want to get line only from black color, draw many separate pixels (or squares if you want lineWidth > 1) between line start and end points. 
 
p.s. sorry for broken fiddle link, system kicked my message even with code included like 10 times ...
