Or to delay running it until load goes (for > example) under 1.00 for 15 mins. I don't know about any generic way, but you can put some shell code into /etc/periodic.conf to exit if load is too high Just a quick and dirty example, exit if 5 minutes avg is higher than 1.1: avg5load=$(top | awk '/load averages:/ { load=$7+0; if (load > 1.1) { print "HIGH" } }') echo $avg5load if [ "$avg5load" = "HIGH" ]; then echo "CPU load is too high" exit 5 fi Kind regards Miroslav Lachman
