应用场景：
在应用运行过程中，难免会有一些线程因等待锁、阻塞导致执行时间慢。这时可以开启TongWeb8的"慢线程检测"功能来排查问题。
当http线程超过"阻塞阈值"时，则日志输出相应线程堆栈。 通过大量收集该日志样本，以判断线程慢的原因。 注：仅收集一、两个该日志，不能说明线程慢在该处。

"中断阈值" 通常不建议开启，因为实际应用场景中线程有业务相关逻辑，中断线程可能造成业务的不完整。 若能确保中断线程无问题，则可开启。相关日志如下：
2023-02-14 15:29:59 [WARN] - Thread [TW-0.0.0.0-8088-1] (id=[61]) has been interrupted because it was active for [26,177] milliseconds (since [2/14/23 3:29 PM]) to serve the same request for [ http://192.168.55.159:8088/webtest01/TestServlet] and was probably stuck (configured interruption threshold for this StuckThreadDetectionValve is [25] seconds). java.lang.Throwable

。。。。。。。
2023-02-14 15:30:01 [WARN] - Thread [TW-0.0.0.0-8088-1] (id=[61]) was previously reported to be stuck but has completed. It was active for approximately [26,177] milliseconds.
"中断阈值"只中断TongWeb的http线程，若应用自建线程出现阻塞，可通过"监视管理"->"阻塞线程"查看，该功能为监控的JVM所有线程。"强停"功能同样谨慎使用。
重点说明：当遇到线程阻塞类问题时，主要通过TongWeb提供的线程堆栈来分析问题，从应用侧来解决。对于"中断阈值", "阻塞线程"的"强停"功能需谨慎使用。
若http通道的线程和队列占满则报错如下：
