Cherrypy server completes too many requests

I used AWS cherry-based server to handle some REST API calls. But when the server was deployed and with some serious traffic (about 200,000 requests in 8 hours), the server ended. The error log displays only one type of error.

 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

Is it because cherrypy cannot scale if there are too many requests or something is wrong in the code?

It looks like you forgot more connections than you configured for the operating system. Try checking ulimit -nand increasing it if you can.
