According to Wes Peters: > Wouldn't it be cleaner to limit it by load average rather than number of > jobs? This would tend to allow small, one-shot cron entries that really Problem is that it can be easily defeated... Sendmail has this kind of setting (queues everything at load >8, stop accepting at load >12) but, when you're under a mail storm, sendmail will fork childs so fast that you'll end up with more than one hundred of them _before_ it will be able to find that the load is too much (am I clear here ? :-)). That's how, with the default settings, you can have more than 170 simultaneous sendmails on a poor 486/33 with 16 MB.
