Question

我有一个Mono .NET应用程序，它使用ppatierno.AzureSBLite从Azure ServiceBus接收数据。

代码很简单：

var factory = MessagingFactory.CreateFromConnectionString(connectionString);
var client = factory.CreateEventHubClient(eventHubEntity);
var group = client.GetDefaultConsumerGroup();
var receiver = group.CreateReceiver(partitionId, startingDateTimeUtc);
EventData = receiver.Receive();

在运行64位Ubuntu 16.04的虚拟机上，使用Ubuntu的Mono软件包，它可以完美运行。

在运行Ubuntu 14.04的构建服务器上，在64位16.04 chroot中（因此chroot环境应该具有与VM相同的所有用户域包），使用Ubuntu的Mono包，我收到以下错误：

如果我正确理解strace输出，则无效主机正在创建IPv6套接字并尝试直接连接到IPv4地址：

connect(4, {sa_family=AF_INET, sin_port=htons(5671), sin_addr=inet_addr("52.176.47.198")}, 16) = -1 EINVAL (Invalid argument)

当正常运行的主机使用类似dual-mode sockets的内容将IPv4地址正确表示为IPv6地址时：

connect(4, {sa_family=AF_INET6, sin6_port=htons(5671), inet_pton(AF_INET6, "::ffff:52.176.47.198", &sin6_addr), sin6_flowinfo=htonl(0), sin6_scope_id=0}, 28) = -1 EINPROGRESS (Operation now in progress)

鉴于Mono及其依赖项内部正在发生这种情况，我该如何排除故障并解决此问题？
