java - EJB 异常 : Channel Channel ID fc7b3f27 (outbound) of Remoting connection 31ad98ef to localhost/127. 0.0.1:4447 无法再处理消息

Question

我正在使用 JBOSS 7 服务器，其中包含我部署的应用程序。我创建了一个 java 应用程序来连接到部署在服务器上的 ejb。连接完美，服务器开始处理我的请求。经过一些处理后，它出现以下异常:

Channel Channel ID fc7b3f27 (outbound) of Remoting connection 31ad98ef to localhost/127.0.0.1:4447 can no longer process messages

有人知道这是什么意思吗？

奇怪的是，我有一个虚拟机，我在那里复制了完全相同的步骤，一切都很顺利。 java应用程序成功执行。我尝试在 JBOSS 社区页面上搜索，但找不到任何内容。

这是我遇到的某种限制吗？

当 java 崩溃时，我在我的应用程序中看到过这样的异常。检查/var/log/messages 是否 java 崩溃了...我的应用程序中的 Java 由于“内存不足”问题而崩溃了。
