应用程序托管在JBoss6（版本6.0.0.Final）中。
在生产环境中，我有时会看到以下错误：

偶尔每周发生一次，并且在第一次发生后的下一分钟会出现这样的例外情况，使整个应用程序挂起。 appserver重新启动后，应用程序正常工作。
在重新启动之前，日志中有242个相同的错误：

应用程序本身是一组SOAP Web服务和动态JSF / Richfaces Web页面。 大多数逻辑都位于无状态bean（@Stateless）中。
我的猜测是，有时调用Web服务需要花费太多时间，导致EJBTransactionRolledbackException。问题是为什么有时会挂起整个应用程序？此外，异常堆栈跟踪不包含应用程序代码中的调用。
可不是因为用完了池（无状态bean对象池）？
