When I installed Ubuntu 12.10, one of the benefits I was looking for was to go without restarting the OS for months. But every 2 days or so the system gets heavy and it's not the same switching between the softwares as it is during the fresh boot. I usually run multiple softwares like JDownloader, Transmission Bit Torrent Client, Firefox (5 to 8 tabs approx.), access another computer's hard drive, music player/vlc player I do need the feel to restart and I do.
A lot of times I also have trouble killing tasks, specially Movie Player. After one or two times, nighters it opens nor the task gets killed. This might be a separate issue but I mentioned anyhow.
Is it possible to go for months without restarting Ubuntu 12.10?
