I recently noticed my kubuntu lucid laptop was using roughly 200Mb more memory than I was used to (and it started to swap and slow down under load).
My first suspicion was KDE 4.4.2, but closer examination revealed no obvious memory leaks...and no process seemed to eat up all that memory. Also, the memory load was heavy even without a running X session, so I concluded I'd have to dig a little deeper.
After retracing my recent steps, I recalled that I had installed 'ureadahead' to see if it could improve my boot speeds. So I decided to uninstall it to see if it made a difference, and so far it looks like it did the trick...memory loads have dropped to what I am accustomed to.
After finding out the 'probable' cause, a search revealed this bug: https://bugs.launchpad.net/ubuntu/+s...ad/+bug/501715
So if you're experiencing high memory loads, 'ureadahead' may be the cause (haven't done extensive testing yet, so I can't be 100% sure)
