Hidden memory leak after updates on arch64
I wasn't sure what would be right place to post this so I decided to put this here since I am using 64-bit arch.
I've seen lot of memory issue threads on forums but most of them are just misunderstandings about buffers or not knowing how to use top or such.
My story begins with my computer being on for 2 months straight (from 18th march to 18th of may), with constantly less than 200 MB when I leave my computer idle with not much running. That was true even after two months uptime. There were updates on pacman during that time which I did periodically. Then on 18th of may I was forced to boot for some reason, and after that I have not been able to keep my computer up for more than a week due to memory usage buildup.
When I boot my computer it uses only 130 MB of RAM, but only after 2 days up, it already is using 550 MB of RAM.

Re: Hidden memory leak after updates on arch64
Press capital 'M' in top to sort by memory usage. That will make it easier to read.

Re: Hidden memory leak after updates on arch64
Try ps_mem from AUR. I'm convinced that top/htop/free are broken. They all produce the same results and they all show me absurd numbers. This isn't to say that you don't have another problem, but it will show you something much different.
