Very low RAM using KDE in Arch Linux


Earlier today I was reading a webpage while installing an application when suddenly my harddrive starting reading/writing like crazy and my screen practically locked up. I went to tty1 and did "top" to see if there was a single application causing some horrible infinite loop or eating too much memory. Nothing stuck out, so I rebooted my machine. While it was rebooting (since it was still being slow), I looked at the "Mem:" line from "top" and saw that even the 4 GB of swap was exceeded by an entire GB. As of writing this, I only have 20MB of available cache, and it occasionally dips as low as 8MB.
I've done some searching online, and I'm seeing people complaining about X using 250MB of the available memory, and mine is far worse (mine is using a little over 1GB of memory). Some were saying that it is caused by KDE effects (mine are disabled).

Any thoughts?
I luckily have another partition on this computer, and I may nuke my Arch partition and start anew if nobody has any ideas.

Thanks.

Here's what "top" looks like:

Sorry, but I can't see any problems here, according to your top-output your systems seems to be running fine.

I agree that from that top output you have 663 MB of RAM being used, and no swap being used. I guess normal with KDE.

You will need to post the output of top when it happens again, or post the program that is using up all the RAM, usually at the very top of top.

You can "gag" Flash with this Firefox plugin (it can be a lifesaver):
