Hello, the amount of memory you need depends on what Django does and how many workers (instances of Django) you run (which usually depends on how many requests you are getting and how I/O intensive your Django application is). For many applications, 512 MB is enough.
Why are you worried? The only symptom you describe is that your free memory is decreasing. This is absolutely normal. The operating system doesn't like RAM that is sitting down doing nothing, so it will do its best to make free RAM nearly zero. Whenever there's much RAM available, it uses more for its caches. How much memory is your Django app consuming? You can find out by executing "top" and pressing "M" to sort by memory usage.
