Cherrypy服务器关闭了太多的请求

Question

我在AWS上使用基于cherrypy的服务器来处理一些REST API调用.但是在部署服务器和一些严重的流量(8小时内大约200,000个请求)时,服务器结束了.错误日志仅显示一种类型的错误.

 ENGINE Error in HTTPServer.tick
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/CherryPy-3.2.2-py2.7.egg/cherrypy/wsgiserver/wsgiserver2.py", line 1837, in start
  File "/usr/local/lib/python2.7/dist-packages/CherryPy-3.2.2-py2.7.egg/cherrypy/wsgiserver/wsgiserver2.py", line 1887, in tick
  File "/usr/lib/python2.7/socket.py", line 202, in accept
error: [Errno 24] Too many open files

这是因为如果请求太多,或者代码中有什么问题,cherrypy无法扩展吗？

听起来您积压的连接数超出了操作系统配置允许的连接数。ulimit -n如果可以的话，尝试检查并增加它。
