An RSS page can be a known copy of a page in the filesystem, and if so then the kernel can reclaim the physical RAM for another use because the filesystem has a copy. Such a page is as good as swappable, even when there is no swap space. Processes such as anaconda, Xserver, metacity [window manager] typically have thousands of resident pages from dozens (or even hundreds) of shared libraries. -- _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
