python - 操作错误 : (2001, "Can' t 创建 UNIX 套接字 (24)")

Question

我正在使用 django-1.2 和 python-2.6，并且我正在使用 mysql 服务器。

工作一段时间后 - 选择和更新记录，我收到此错误:

Exception in thread Thread-269:
Traceback (most recent call last):
  File "/usr/lib64/python2.6/threading.py", line 532, in __bootstrap_inner
  File "dispatcher.py", line 42, in run

  File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 187, in __init__  
OperationalError: (2001, "Can't create UNIX socket (24)")

这是我的 dispatcher.py 的第 41,42 行:

dataList = Mydata.objects.filter(date__isnull=True)[:chunkSize]
print '%s - DB worker finished reading %s entrys' % (datetime.now(),len(dataList))

知道为什么我会收到此错误吗？
我尝试谷歌搜索但找不到答案。

我正在使用 django 连接到数据库 - (我正在使用 localhost)

在我的机器上，errno==24 的定义如下

#define EMFILE          24      /* Too many open files */

这意味着您的文件描述符已用完。您的应用程序通过一次又一次打开(而不是关闭)文件描述符来“泄漏”文件描述符。
