Python 以嵌套节点组为目标失败，返回“0”；仆从没有回来。[没有回应]”；，尽管主机通过其他标准作出响应

我对嵌套节点组有一个奇怪的问题，因为我似乎无法将它们作为目标。这是我的主配置文件的节点组部分：

---

/etc/salt/master:

nodegroups:
  linuxlabs: 'E@^pubbox'
  linuxtest: 'N@linuxlabs'

---

下面是一个在嵌套节点组上失败的目标示例，尽管可以分别以父节点组和主机为目标

[root@salt-master ~]# salt 'pubbox10.example.com' test.ping
pubbox10.example.com:
    True

[root@salt-master ~]# salt 'pubbox44.example.com' test.ping
pubbox44.example.com:
    True

[root@salt-master ~]# salt -N linuxtest test.ping
pubbox10.example.com:
    Minion did not return. [No response]
pubbox44.example.com:
    Minion did not return. [No response]

[root@salt-master ~]# salt -N linuxlabs test.ping
pubbox44.example.com:
    True
pubbox10.example.com:
    True

---

添加“-l debug”或“-l trace”实际上并没有透露太多信息。实际上，在-l调试输出中，它显示嵌套节点组正在解析为正确的主机名。在“-l trace”输出中，终端被无情地垃圾邮件发送，并显示相同的消息：

[root@salt-master ~]# salt -N linuxtest test.ping -l trace

^^此消息重复2000多次，几秒钟后在以下位置结束：

我尝试了嵌套节点组的一些变体。例如,我没有让父节点包含"E"前缀,而是将其改为"L",并显式列出主机名。同样的结果

我是不是偶然发现了一只虫子？还是我对节点组的配置有误？值得一提的是，我检查了本版本和当前版本的Salt之间的发行说明，没有找到任何关于解决嵌套节点组问题的内容。

这似乎是一个bug。您介意在SaltStack的github问题跟踪程序上打开一个问题吗？

谢谢
