"Are you finding less and less storage space on your root filesystem, but you can't figure out where it's all going? You may have a temporary (/tmp) directory gone amok."
"The /tmp directory is a world-writable, world-readable directory that almost every Linux application uses to hold temporary files. Unfortunately, many Linux applications are also in development or pre-release (among them, popular versions of both KDE and GNOME) and don't properly clean out their /tmp files, especially when they crash. You may just have megabytes of storage being wasted in /tmp."
