I don't have anything open on my computer and the RAM usage is 525/1.96GB according to my Conky display.
What is using up all this memory? Conky?
Is ther something I can post back that may offer a hint of what is going on?
You can check what's using all that memory with htop
I've made a huge mistake
If you use "free" you must read the field +/-buffers / used. The more used space is only caching.
So you have 75% of your RAM free. What would you consider a reasonable number?
