Linux 用于引用同一套接字的多个inode

我有一组应用程序，它们都绑定到单个Linux机器上的同一个多播UDP端口。（在本例中为23003）。应用程序是多线程的，因此在某些情况下，它可能会在不同线程中多次绑定到同一应用程序中的同一端口

也就是说，当我执行lsof时，我看到从一个pid到多个inode的引用都引用同一个UDP端口。那很好；然而，当我查看多个应用程序时，有时inode编号是唯一的，这是我所期望的，有时它不是唯一的；这意味着多个应用程序引用同一个套接字inode

我希望有一个或另一个，但不是两个都有。请参见下面的输出。在第一个输出中，PID 18774和其他有两个不同的inode（一个28267669，每个应用程序的另一个唯一），都指向端口20003。在第二个命令中，您可以看到所有正在查看inode 28267669的应用程序。有人能解释一下吗？为什么我同时看到唯一和非唯一inode引用
