[edit] Plagarism
The last two sections (cause of thrashing and limiting the effects of thrashing) appear to be copied word-for-word from the textbook Operating System Concepts (Silberschatz, Galvin, Gagne). —Preceding unsigned comment added by 72.138.253.205 (talk) 15:06, 6 April 2008 (UTC)
[edit] Engineering
Is this term commonly used to refer to work? I'm a software engineer and I often hear thrashing to mean what happens when engineers are switching between projects far too often. Since the term has its roots in our field, is it exclusive to us, or does it exist in other fields? Should it be mentioned here?

IMHO, an animation of "thrashing" would be worth "a million" words. (Since "a picture is worth a 1000 words." An animation is a ~1000 pictures, thus(1000X1000=1,000,000) "a million" words.)
[edit] Permaswap
I'd like to see the term "permaswap" added to this article. It's a common way to describe the situation where the system is almost completely stalled, and the disk is going crazy. See for instance this link [1] or just do a Google search for the term. There are lots of references, but the term doesn't exist in Wikipedia. leifbk 09:26, 5 October 2007 (UTC)
[edit] Practical considerations
The advice to increase memory is in principle a good one, though on some systems I believe that this will not always solve the problem, depending on what programs are used. For example, running a virus checker over a disc drive may result in any caches being flushed, and any other program will slow down to snail's pace. This seems to be quite common in systems such as Windows XP. This is hinted at in the article, but specific details are not given. Programs which look at significant parts of storage discs, or which create large files themselves (e.g sound, video recorders), and programs which use large temporary memory or files (e.g photo manipulation programs) are more likely to cause thrashing problems than programs which only use a small amount of memory, and few files.
