What is in code.py that you are using as the FCGI bridge to your
application. If you are using runfcgi() from web.py, from reading code
of flup, it will default to enable multiplexing.
def runfcgi(func, addr=('localhost', 8000)):
"""Runs a WSGI function as a FastCGI server."""
import flup.server.fcgi as flups
return flups.WSGIServer(func, multiplexed=True,
bindAddress=addr).run()
In other words, looks like it will attempt to create multiple threads.
If this is true, then that is why your virtual memory use is so high.
For starters, instead of calling runfcgi(), use instead something
like:
import flup.server.fcgi as flups
return flups.WSGIServer(func, multiplexed=False).run()
Replace func with what you passed to runfcgi().
See if that drops virtual memory usage.
Someone else will need to step in an explain how flup works out how
many threads to run when multiplexing is enabled as I don't know.
