官方文档对weblogic stuck线程的描述

      Tuning the Stuck Thread Detection Behavior 

     ---检测stuck线程的行为

     ---正在执行的线程队列变为stuck状态，weblogic服务会自动检查的到。因为stuck的线程不能完成当前的任务和接受新任务，当诊断一个stuck线程，服务就会记录日志。

         WebLogic Server diagnoses a thread as stuck if it is continually working (not idle) for a set period of time. You can tune a server’s thread detection behavior by changing the length of time before a thread is diagnosed as stuck, and by changing the frequency with which the server checks for stuck threads. 

    ---weblogic服务如何诊断一个线程为stuck，如果此线程在一段时间内总是在不断的工作。在一个线程在被诊断为stuck之前，你可以改价检测的时间长度，并通过改变频率，用于服务器检测stuck线程。

      Although you can change the criteria WebLogic Server uses to determine whether a thread is stuck, you cannot change the default behavior of setting the “warning” and “critical” health states when all threads in a particular execute queue become stuck.

      ---虽然你能改变weblogic诊断线程是否为stuck的标准，但你无法更改设置“警告”和“严重”的健康状态时，在一个特定的执行队列中的所有线程被卡住的默认行为。
