Question

当我使用pynamodb模型时，我的Python服务器正在随机生成OSError: [errno 14] Bad Address。此问题在我的任何pynamodb模型中均发生，并且很少发生。大多数电话将成功。

当botocore从文件/usr/local/lib/python3.7/site-packages/botocore/data/dynamodb/2012-08-10/service-2.json中读取时，将引发错误。我不知道为什么会这样，为什么它是随机的。

我正在使用 Python 3.7.3 ， Django 2.2.2 ， Pynamodb 3.3.3 和 Gunicorn 19.9.0 。我正在由Kubernetes管理的Docker基础python:3.7-slim上运行服务器。

示例：

  >>> from pynamodb.models import Model
  >>> class User(Model):
  ...     hash = UnicodeAttribute(hash_key=True)
  ...     username = UnicodeAttribute(null=True)
  ...     class Meta:
  ...         table_name = "user"
  ...         read_capacity_units = 10
  ...         write_capacity_units = 10
  ...         region = "us-west-2"
  ... 
  >>> user = User.get("valid-user-id")
  Traceback (most recent call last):
  File "<input>", line 11, in <module>
      user = User.get("valid-user-id")

    api_version=api_version)
  File "botocore/loaders.py", line 132, in _wrapper
    data = func(self, *args, **kwargs)
  File "botocore/loaders.py", line 383, in load_service_model
    model = self.load_data(full_path)
  File "botocore/loaders.py", line 132, in _wrapper
    data = func(self, *args, **kwargs)
  File "botocore/loaders.py", line 420, in load_data
    found = self.file_loader.load_file(possible_path)
  File "botocore/loaders.py", line 173, in load_file
    payload = fp.read().decode('utf-8')
  OSError: [Errno 14] Bad address

Botocore提高OSError：[errno 14]错误的地址
