Better let nagios monitor: - fork rate by observing kern.lastpid sysctl over time - nr. of processes running - top 10 processes sorted by resident memory (res not size in top(1)) Those are the actual symptoms of something going wrong that can cause a system to start swapping heavily. 3MB swap is not 'heavily' and is nothing to worry about.In fact, a high fork rate can DOS a system pretty well, without the machine ever going into swap. -- Mel Problem with today's modular software: they start with the modules and never get to the software part.
