“在查询python期间失去与MySQL服务器的连接

Question

我正在使用@transaction.atomic decorator 我正在使用python和django 我得到了这个错误：

Internal Server Error: /create_project
Traceback (most recent call last):
  File "/usr/local/lib/python3.4/dist-packages/django/db/backends/base/base.py", line 239, in _commit
    return self.connection.commit()
  File "/usr/local/lib/python3.4/dist-packages/pymysql/connections.py", line 422, in commit
    self._read_ok_packet()
  File "/usr/local/lib/python3.4/dist-packages/pymysql/connections.py", line 396, in _read_ok_packet
    pkt = self._read_packet()
  File "/usr/local/lib/python3.4/dist-packages/pymysql/connections.py", line 656, in _read_packet
    packet_header = self._read_bytes(4)
  File "/usr/local/lib/python3.4/dist-packages/pymysql/connections.py", line 702, in _read_bytes
    CR.CR_SERVER_LOST, "Lost connection to MySQL server during query")
pymysql.err.OperationalError: (2013, 'Lost connection to MySQL server during query')

The above exception was the direct cause of the following exception:

我该怎么办？？ UPD：我正在使用cloud 9 ide（c9.io），因为c9服务器不够健壮，这是否可以与性能问题联系起来？
