谷歌AppEngine Python OSError启动时“打开的文件太多”

Question

我在OSX、python2.7和GAE 1.8.8上使用ubuntu13.10运行在VM中。

读取dev_appserver.py会导致以下错误：

INFO     2013-12-10 03:53:30,046 api_server.py:527] Saving search indexes
Traceback (most recent call last):

有什么想法吗？

检查您的linux系统上的共享内存参数kern.sysv.shmseg，并通过增加它来设置它。

若要查看共享内存参数，请使用：

sysctl -A | grep shm

若要更新该参数，请编辑文件：

sudo nano /etc/sysctl.conf
