Sun应用程序服务器中的应用程序在处理几条消息后挂起

Question

应用服务器Sun appserver 8.1 JVM - java 1.5.0.11

我们在Sun application Server9.x中部署了一个JMS接收器来处理消息，在处理了大约50多条appserver挂起的消息之后。在重启时，50多条消息被处理并再次挂起。

没有抛出异常/错误(我们修改了代码以捕获Throwable并在严重模式下记录)。因此，行为不能归因于代码或消息，因为它们被重新处理。

我将非常感谢任何f/b的建议，我不能加载整个堆栈，有没有办法附加一个文件？

线程被阻塞，在没有上下文的情况下无法进行分析。

考虑使用jvisualvm进行更好的调查。它还可以检测死锁。
