我们在 Tomcat 版本:7.0.23 中实现了 Servlet 3.0 AsyncContext。
它正在RHEL 6.1 using OpenJDK version 1.6.0_24,64-bit
服务器中运行
该应用程序大部分工作正常。当网络出现一些干扰时,来自服务器的更新无法到达客户端,因为存在“ ClientAbortException: java.net.SocketException: Broken pipe
”异常。被捕获并忽略。
这发生在行中,
asyncContext.getResponse().getWriter().println(updateStr);
在这个 Tomcat 发疯并且将 URL 路由到意外的 servlet 之后。例如,使用 /query 映射到名为 SessionManager 的 servlet,URLmysite.com/index.html
被路由到 SessionManager servlet。只有重启tomcat才能解决问题。
关于为什么会发生这种情况以及如何解决这个问题的任何指示?
只是为了添加更多数据,以下是异常的堆栈跟踪。
