org.mmbase.applications.crontab
Class MemoryWarner

java.lang.Object
  org.mmbase.applications.crontab.AbstractCronJob
      org.mmbase.applications.crontab.MemoryWarner

All Implemented Interfaces:

Runnable, CronJob

public class MemoryWarner
extends AbstractCronJob

Performs Runtime.gc(), and if afterwards the used memory is above a certain fraction of the maximally used memory, mail a warning to someone. The idea is that that someone can then take action, like exploring what is the matter, or clearing some caches. You need mmbase-email.jar installed for this.
