在java应用程序中挂起问题

时间：2017-10-14 17:28:56

标签： java multithreading sockets threadpool hang

下面是线程转储sneapet。运行几天后应用程序正在挂起。 怀疑

  • java.net.SocketInputStream.socketRead0 ，这可能是root问题吗？

正在处理ID 14226，请稍候... 调试器连接成功。 服务器编译检测到 JVM版本是25.121-b13 死锁检测：

没有发现死锁。

编辑（摘自评论）

我们提供的读取超时和连接超时。但是，I / O异常通常会在连接丢失时出现。但在悬挂情况下，我们也没有任何例外。

SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
schemeRegistry.register(new Scheme("https", 443, SSLSocketFactory.getSocketFactory()));

PoolingClientConnectionManager httpConnectionManager = new PoolingClientConnectionManager(schemeRegistry);
httpConnectionManager.setMaxTotal(500);
httpConnectionManager.setDefaultMaxPerRoute(200);

DefaultHt‌​tpClient httpClient = new DefaultHttpClient(httpConnectionManager);
httpClient.getParams().setParameter(ClientPNames.ALLOW_CIRCU‌​LAR_REDIRECTS, true);

requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);
requestFactory.setConnectTimeout(30000);
requestFactory.setReadTimeout(30000);

knlogger.info(methodname,"Created requestFactory");

虽然无法确定我们现在掌握的信息量是多少，但我可以假设应用程序“挂起”的一个可能原因：

您正在使用阻止I / O.代码正在等待几个线程（socketRead0处）的下一个数据包。这可能是正常的，但很可能网络连接丢失（例如路由器上的网络中断等）。由于传输层完全是底层操作系统的责任，因此可能无法长时间通知应用程序关于连接中断（例如，直到操作系统无法在保持连接配置时多次向keeppient发送keepalive消息）或直到应用程序本身将尝试发送同一个套接字上的数据。

为防止发生这种情况，您应该考虑以下解决方案之一：

  • 设置读取超时（默认情况下，JVM类配置为“无超时”）并在超时后重新连接
  • 启用连接保持活动状态（如果可能）。检测到连接丢失的速度取决于操作系统中的协议设置。
  • 让系统交换心跳 - 例如3次错过的心跳意味着连接丢失。

在任何情况下，您都应该准备好处理连接异常并尝试重新连接。
