I've been trying to stress 2.6.15-mm3 by putting a *lot* of load on it and seeing if it stays alive, how it copes, how long it seems to take to recover etc. While doing that I've done some test runs that start thousands of processes and the load average quickly shoots up to several hundred and eventually reach 1000 - when it continues to climb it goes to 1023 and then wraps down to small numbers like 4-5 and then continue climbing from there. Once I kill all my processes it slowly goes down to zero, then wraps back to ~1000 and continues to climb down from there until it's eventually back to normal. Is this expected behaviour? -- Jesper Juhl Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html
