Thanks for all of your tips Graham. Although I am starting to
understand how this works, I think I need to learn a lot more about
it.

It is hard to tell with direct access and ability to experiment, so
suggest what you do is use configuration:
<VirtualHost xxx:80>

user=nobody group=nogroup python-eggs=/tmp
WSGIScriptAlias /foo /home/some/path/foo.py

What you have is one Apache parent process. This is effectively the

for spawning off the mod_wsgi daemon process. You would then have 2

Dear Graham,

Thanks a lot for your reply.
I just checked with ldd command. here is the output:

Thank you for the tips. I have a couple of more questions, although
this is more related to Apache. Beack to the ServerLimit option. I
currently have 2 sites with the configuration I posted in my first
post. Say I have 10 sites with minimal traffic, would it still be good
to do ServerLimit 2? Or would I change that as my number of sites goes

For this application, what does the WSGIScriptAlias line say?
If it is something like:
WSGIScriptAlias /xyq_active /some/path/script.wsgi
with URL used to access it that component being:
/xyq_active/get_cdkey/
then may be okay. If 'xyq_active' isn't the mount point however, then

If you have a site which will be infrequently accessed, then using
inactivity-timeout will help in dropping memory usage back down when

Graham,

As always, thank you for your help. You are correct that it was an
earlier version of mod_wsgi. I assumed the latest version of Ubuntu
would carry a later version of mod_wsgi.

Is putting the maximum-request and inactivity-timeout the correct
approach to ensuring processes do not grow too large? Or would it be

sys.path.append("/home/ati/tes t")

os.environ['DJANGO_SETTINGS_MO DULE'] = 'get_cdkey.settings'

Post your WSGI script file and urls.py file and will tell you if they
are correct.
The required WSGI script file fiddle is:

I follow the example in that page, there no errors about urls.

I don't know how to "use a workaround in WSGI script file"，what's the
meaning ?

BTW, I have some application runing in django(0.96), upgrading to
