Apache2 with MySQL and Django on 256MB RAM VDS

I have a 256MB RAM VDS with Debian Lenny, Apache2, MySQL, mod_php (and some PHP websites). In this configuration VDS have about 35MB RAM left. So, I installed mod_wsgi (in daemon mode) and some very simple Django site (just for testing, it's one model and Django admin). After that only 25MB lef开发者_运维百科t. It's OK, but after visiting Django admin apache spawns about 6 more processes (and in total I have 9 processes: 1 under root, 7 under www-data and one for mod_wsgi). So, now I have only 6MB left. And after each visit Apache eats more memory and, finally, no memory left and I need to reboot server.

What can I do or read? Of cause, it's possible to extends VDS' RAM, but it's last resort.

You can change Apache conf to keep a smaller process pool.
