To give you a simple example why, suppose the administrator has a cron job that checks the load every minute and sends out an alert if it reached 25. The proposed solution would actually have become a problem. Without going into any details, a "smarter" approach -- eg specifying load limits per job -- would be too much of an effort. A possible solution for the situation you describe would be to preceed your commands with the following test (for a load of 20.00): [ $(awk '{print $1}' /proc/loadavg | tr -d '.') -le 2000 ] || your-job Christian
