if you are using firefox I have noticed recently (maybe last 2 months) it has started using excessive memory. And it seems to get quite large and start paging. Mine is doing it on some websites in no more than a few days, it is getting annoying. I have seen a single firefox process >10G, and on that machine it was paging so I killed it. ps aux | sort -k 6n 6th column is actual memory usage (this number will not show swap usage for a process). The 5th column is virt and it is rather unreliable and I ignore it.
