今天遇到系统无法访问问题，检查日志异常如下。
异常信息
|WARNING|glassfish3.1.2|com.sun.grizzly.config.GrizzlyServiceListener|_ThreadID=14;_ThreadName=Thread-2;|GRIZZLY0023: Interrupting idle Thread: http-thread-pool-28080(4).|#]
根据字面意思理解（Interrupting idle Thread）中断空闲的线程。网上摘取一段资料，https://www.java.net/node/703110
the interrupted message/warning itself is not a bug, it is just an indicator that HTTP request processing (Servlet execution) takes longer than expected (expectation is set by request-timeout setting). You can always disable this feature by setting request-timeout to -1 on an appropriate http-listener like [1]. The default timeout value is set to 15mins, it means one single servlet execution takes longer than 15mins! If this is ok – then just disable the timeout [1], if this is not ok – then there should be something wrong w/ the servlet/webapplication code.
大体意思是，一个servlet请求默认超时为15分钟，如果在高并发情况下，线程很多就会导致线程的堵塞，当达到线程开启上线的时候导致新线程无法开启。
嗯，有点意思了，根据这个资料，我对我的服务做了先调整，我用的是glassfish，调整了超时时间为5分钟，并且增加了最大线程数，如图，
再运行一段时间，看看还会不会再出现这个警告了。
个人分析，在高并发情况下，，每个请求都相应缓慢，而且超时时间为15分钟较长，随着时间增加，服务线程数达到峰值，导致出现此类问题。
后来逐渐有广州花城的，
