google-app-engine - EOFError : EOF read where object expected 错误

Question

最近在GAE上出现了奇怪的错误，比如这个:

Traceback (most recent call last):
  File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 240, in Handle
    handler = _config_handle.add_wsgi_middleware(self._LoadHandler())
  File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 299, in _LoadHandler
    handler, path, err = LoadObject(self._handler)
  File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 96, in LoadObject
    __import__(cumulative_path)
EOFError: EOF read where object expected

不确定故障是在我的应用程序中还是在 GAE 上。还有其他人看到这个吗？

当 3 个或更多 Python 进程读/写同一个 pyc 文件时，很可能是竞争条件。已在 Python 3.3 中修复:http://bugs.python.org/issue13146
