问题
Stop->通过Windows服务启动tomcat 8失败，因为tomcat关闭以某种方式一直在侦听端口8080，并且tomcat无法绑定到端口8080，因此tomcat无法启动
背景
我们的一个构建脚本（重新启动tomcat Windows服务）在几周前开始失败。从假期回来，我现在正试图解决这个问题。据我所知，tomcat配置未做任何更改。
重现问题
Tomcat完全关闭（通过Windows服务停止），没有错误：
10-Aug-2018 19:30:56.860 INFO [Thread-4] org.apache.coyote.AbstractProtocol.pause Pausing ProtocolHandler ["http-apr-8080"]
10-Aug-2018 19:30:56.860 INFO [Thread-4] org.apache.coyote.AbstractProtocol.pause Pausing ProtocolHandler ["ajp-apr-8009"]

10-Aug-2018 19:30:56.985 INFO [Thread-4] org.apache.coyote.AbstractProtocol.stop Stopping ProtocolHandler ["ajp-apr-8009"]
所有tomcat端口均免费：
C:\Windows\system32>netstat -abno | find "80"
TCP 0.0.0.0:49160 0.0.0.0:0 LISTENING 1180
TCP [::]:49160 [::]:0 LISTENING 1180
UDP 0.0.0.0:123 *:* 980
UDP [::]:123 *:* 980
我们可以看到默认的tomcat端口8080是空闲的（列表中不存在）
Windows报告“ apache tomcat”服务将被停止。
任务管理器没有用于“ tomcat8w.exe”的进程
我通过启动Windows服务来启动tomcat，并在catalina日志中获得以下内容：

之后，它将开始部署应用程序。启动后，我运行：
C:\Windows\system32>netstat -abno | find "80"
TCP 0.0.0.0:8009 0.0.0.0:0 LISTENING 5040
TCP 0.0.0.0:49160 0.0.0.0:0 LISTENING 1180

TCP [::]:49160 [::]:0 LISTENING 1180
UDP 0.0.0.0:123 *:* 980
UDP [::]:123 *:* 980
我可以看到端口8009绑定到PID 5040，在taskmanager中它是“ tomcat8.exe”，但是您可以看到端口8080是空闲的，但是由于错误而未绑定：
10-Aug-2018 19:36:50.674 INFO [main] org.apache.coyote.AbstractProtocol.init Initializing ProtocolHandler ["http-apr-8080"]
10-Aug-2018 19:36:50.674 SEVERE [main] org.apache.coyote.AbstractProtocol.init Failed to initialize end point associated with ProtocolHandler ["http-apr-8080"]
java.lang.Exception: Socket bind failed: [730048] Only one usage of each socket address (protocol/network address/port) is normally permitted.
因此，此时构建脚本已成功执行，Windows报告apache tomcat服务正在运行，但是tomcat尚未绑定到端口8080，因此未收到任何新请求。
WORKAROUND
如果我重新启动Windows（服务器），则tomcat服务将启动而不会出现问题，并且tomcat将侦听端口8080。
下一步
tomcat无法绑定到自由端口8080的原因是什么？
或者什么能够阻止Windows显示谁/什么阻止了8080端口？
以前的tomcat实例如何阻止8080端口，但Windows不能显示任何正在运行的tomcat实例？
