java BindException:已在使用的地址:绑定即使端口是免费的

Question

我正在测试torchserve的默认配置..。它的推理api监听端口8080。我得到了这个错误，这意味着端口在使用中。糟糕的是，我仍然让apache进程监听那个端口。我杀了阿帕奇进程。但我还是会犯同样的错误。再次尝试通过更改torchserve的端口配置来使用我确信没有被任何进程使用的端口。仍然有同样的错误。使用TCPView应用程序，我可以看到，已经配置的端口在侦听状态下为torcheserve进程打开了一秒钟。但很快它又被移除了。

所以谁也不知道为什么会发生这种事？我确信这不再是港口冲突的问题了。

我也犯了同样的错误，并通过向config.properties文件中添加以下行来解决它。

grpc_inference_port=7000
grpc_management_port=7001
