Context Broker仅在被问到两次时才响应

所以问题是，当我尝试与Context Broker建立连接时，我是否正在尝试更新实体或读取值。它只在我第二次询问时才响应。

Context Broker版本：0.24.0（我从0.20.0更新，因为我认为这是问题）

示例：

python2.7 GetEntity.py entity_1

输出：

* Asking to http://188.***.**.***:1026/ngsi10/queryContext
* Headers: {'Fiware-Service': 'fiwarefinal', 'content-type': 'application/json', 'accept': 'application/json', 'X-Auth-Token': 'NULL'}
* Sending PAYLOAD:

    "entities": [
        {
            "type": "",
            "id": "entity_1",
            "isPattern": "false"
        }
    ],
    "attributes": []
}

...

当我第二次这样做时：

}

          {
            "name" : "temperature",
            "type" : "int",
            "value" : "8"
          }
        ]
      },
      "statusCode" : {
        "code" : "200",
        "reasonPhrase" : "OK"
      }
    }
  ]
}

示例Nrº2：

curl http://188.***.**.***:1026/version

输出：

curl: (56) Failure when receiving data from the peer

当我第二次这样做时：

<orion>
  <version>0.24.0</version>
  <uptime>0 d, 0 h, 41 m, 27 s</uptime>
  <git_hash><deleted for safety reasons></git_hash>
  <compile_time>Mon Sep 14 17:52:44 CEST 2015</compile_time>
  <compiled_by>fermin</compiled_by>
  <compiled_in>centollo</compiled_in>
</orion>

有时我甚至不得不重启，因为当我检查Context Broker的状态时，它会给我一个错误。我不确定错误，但我认为它类似于“pid文件不存在”

修改

Error COntext Broker

编辑2：

所以我尝试使用Fiware-Figway的脚本：

python2.7 GetEntity.py entity_1

正如预期的那样，由于这个问题，它的工作时间只有一半。
