Nservicebus System.Net.HttpListenerException:未能侦听前缀';xxxx和x27;因为它与计算机上的现有注册冲突
无论何时部署我们的组件,我们都会收到以下异常。有时组件本身不会启动,有时服务控制台可能会说已启动,但服务不会处理任何消息。 这个错误非常简单。还有另一个HttpListener仍在侦听前缀Nservicebus System.Net.HttpListenerException:未能侦听前缀';xxxx和x27;因为它与计算机上的现有注册冲突,nservicebus,nservicebus3,nservicebus-distributor,Nservicebus,Nservicebus3,Nservicebus Distributor,无论何时部署我们的组件,我们都会收到以下异常。有时组件本身不会启动,有时服务控制台可能会说已启动,但服务不会处理任何消息。 这个错误非常简单。还有另一个HttpListener仍在侦听前缀 NServiceBus.Hosting.GenericHost System.Exception: Failed to start listener for http://localhost/products/ make sure that you have admin priviliges --->

问题:
为什么服务控制台报告服务已停止,即使进程在机器上仍处于活动状态
注意:若要重现此问题,您必须使用NServiceBus.Master配置文件将主机安装为Windows服务,然后尝试重新启动服务,您可能需要更多尝试才能解决此问题
更新:
当我在HttpChannelReceiver.Start()上读取NSB代码时,它会在新线程上启动侦听器
此侦听器线程仅在ServiceHost杀死当前进程的内存时被回收,直到ServicHost收集它,此线程将被阻止退出当前进程 这应该已经在v4中修复,请参见这应该已经在v4中修复,请参见我在NSB上为此创建的问题。我在NSB上为此创建了一个问题。
