Hi, Yes, the CPU usage of the process which runs hudson.war scales to 250+%. It doesn't run hudson.war alone, but it also runs the Maven, ANT, jboss and other tasks required by the jobs. And sometimes because of the intensity of the jobs or so, it goes out of PermGenSpace and I have to restart jenkins for resolving that. I run jenkins on a 32 bit server in Red Hat Linux. Can you tell me the good MAVEN_OPTS configuration settings? I think MAVEN runs out of memory when it does something with very high intensity and things break loose. I am not able to get the optimum MAVEN settings for Jenkins.
