How many runs of these builds do you have hanging around? I had this problem before, and it appeared that the results of every build (except for the log files and the artifacts) are held in memory. In my case, I stored the environment of every build I ran and our environments get really big (as in, classpaths get truncated for exceeding Linux’s max size for environment variable values). Trimming down to (say) the last week of builds helped out a lot.
Also, you may want to explicitly set your max heap space, but that’s more a Java 7 thing than a Jenkins thing. --Rob From: jenkinsci-users@googlegroups.com [mailto:jenkinsci-users@googlegroups.com] On Behalf Of Ben Erridge Sent: Wednesday, October 03, 2012 11:34 AM To: jenkinsci-users@googlegroups.com Subject: Jenkins using massive amount of ram I have installed jenkins on a fedora core 17 linux server. When I start jenkins it seems to take a ton of ram (12GB+). I start jenkins with the command. I am using open jdk 1.7 start command is /usr/bin/java -Djava.awt.headless=true -DXmx4g -XX:MaxPermSize=128m -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=8080 --ajp13Port=8009 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20 It doesn't seem reasonable to me. Maybe I am doing something wrong? I only have 5 builds setup...
