I'd say that a load average of 15 and 20 respectively is enough to justify some proactive if not drastic actions. With Sendmail continuing to send emails you'll otherwise risk that the entire server goes down, which will also have impact on all users.
Could somebody help me put this into context please.What is the average load on a RaQ3? I'm about to setup a RaQ3 for our company, and it will be hosting 150 user accounts (all of whom rely on email), what sort of load average (on this scale) would this be ?
Thanks, Kam.
