One possibility is that although you think you are using daemon mode,
you aren't, and that Apache compiled with worker MPM. This can occur
if you don't have WSGIProcessGroup directive set properly to refer to
daemon process group setup using WSGIDaemonProcess.
Post the mod_wsgi bits of the Apache configuration, include any
VirtualHost, Directory, Location context they are defined in.
In your per request debug also print out:
print >> sys.stderr, environ.get('mod_wsgi.process_group')
print >> sys.stderr, environ.get('mod_wsgi.application_group')
print >> sys.stderr, environ.get('wsgi.multithread')
print >> sys.stderr, environ.get('wsgi.multiprocess')
If mod_wsgi.process_group prints out as empty string, you are running
in embedded mode. If multithread is true shows that running in
multithreaded process and not single threaded process as you expect
and thus also why result may be different each time.
You could also print out:
print >> sys.stderr, threading.currentThread()
to show what Python thinks the thread is each time.
