地址已经在使用:JVM_Bind 但没有使用端口和 netstat 列出进程 [英] Address already in use: JVM_Bind but no process is listed using port with netstat

问题描述

我有一个 Java 进程，它使用 ServerSocket API (Java 8) 并绑定到本地端口 12000.进程在 Windows 服务包装器 (exe4j) 下运行.我有一个在凌晨 4 点运行的计划任务，它停止服务并在几秒钟后重新启动它.该流程已在 400 多个客户地点安装.

I have a java process that make use of ServerSocket API (Java 8) and bind to the local port 12000. Process runs under a Windows service Wrapper (exe4j). I have a scheduled task that runs at 4am that stop the service and restart it after a couple of seconds. That process is installed over 400 customers locations.

一切都很顺利，直到上周五.一些进程未能在凌晨 4 点正确重启.在我能够连接和验证的 2 台服务器上，重新启动失败，同时显示地址已在使用中:JVM_Bind".系统似乎仍在使用端口 12000.

Everything was running smooth until about last friday. A few processes failed to restart properly at 4am. On 2 servers I was able to connect and verify, the restart failed with both a "Address already in use: JVM_Bind". It's seems that the port 12000 was still in use by a the system.

我使用了所有我知道的工具(processexplorer、tcpview、netstat -ano、命名)试图找到进程......但没有成功.只有重新启动机器才能解决问题.但是一两个晚上后问题又来了.

I used every tools (processexplorer, tcpview, netstat -ano, name it) I know to try to find the process... with no success. Only a machine reboot fixed the issue. But problem came back a night or two later.

一些阅读后，我看到我正在做一个无限超时的 sockect.accept() 所以我把它改成了<代码>socket.setSoTimeout(15000);socket.accept();相反.

After some reading, I saw that I was doing a sockect.accept() with infinite timeout so I changed it for socket.setSoTimeout(15000); socket.accept(); instead.

我已经安装了新版本，但问题仍然存在.

I putted the new version in place but the problem is still there.

机器获得了 Windows 更新.我使用完全更新的相同 Windows 版本进行了测试，但无法重现.

Machines got Windows updates. I did tests with the same Windows version fully updated but I can't reproduce.

我现在没有办法了.

任何想法谢谢

推荐答案

Windows 更新影响进程关闭后地址/端口的释放.

A windows update affected the release of address/port after process shutdown.
