tomcat 接收请求出现 java.io.IOException: Too many open files

[狂热的土豆]

我写了一个简单的servlet，放在tomcat里跑，然后写了一个循环向tomcat发请求，一秒钟两条，几个小时后tomcat报出
SEVERE [http-nio-80-Acceptor-0] org.apache.tomcat.util.net.NioEndpoint$Acceptor.run Socket accept failed
java.io.IOException: Too many open files
at sun.nio.ch.ServerSocketChannelImpl.accept0(Native Method)
at sun.nio.ch.ServerSocketChannelImpl.accept(ServerSocketChannelImpl.java:422)

at org.apache.tomcat.util.net.NioEndpoint$Acceptor.run(NioEndpoint.java:686)
at java.lang.Thread.run(Thread.java:745)

文件句柄数已经设置成65535

代码贴出来一下，是不是操作了文件，然后没有close掉。

是不是有些超时断开的时间调短点 好像多了本来就会这样?

看着是io异常，检查一下是否有文件类的操作，如有看流是否正常关闭

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, UnsupportedEncodingException { Map parameterMap = request.getParameterMap(); Map<String, String> sysEnv = System.getenv(); Properties props = new Properties(); props.setProperty("zookeeper.connect",sysEnv.get("zookeeper_connect")); props.setProperty("serializer.class",sysEnv.get("serializer_class")); props.setProperty("metadata.broker.list",sysEnv.get("metadata_broker_list")); String topic = sysEnv.get("topic"); Producer<Integer, String> producer = new Producer<Integer, String>(new ProducerConfig(props)); StringBuffer analysisMessage = getAnalysisMessage(parameterMap); producer.send(new KeyedMessage<Integer, String>(topic, analysisMessage.toString())); } private StringBuffer getAnalysisMessage(Map parameterMap) throws UnsupportedEncodingException { StringBuffer queryString = new StringBuffer(""); for(Iterator it = parameterMap.entrySet().iterator();it.hasNext();){ Map.Entry<String, String[]> en = (Map.Entry<String, String[]>)it.next(); String k = en.getKey(); String v = en.getValue()[0]; v = new String(v.getBytes("UTF-8")); queryString.append(k).append("=").append(v); if(it.hasNext()){ queryString.append("&"); } } return queryString; }
