Environment: Linux/Windows7, Java 1.6.0.03/37 or 1.7

I downloaded jenkins.war and after the initial setup using the following script/command, I downloaded some plugins(10-15) and tried to restart Jenkins, it worked. Then, I got some more plugins (30-40 in total) and either I chose Install or download+then+install, Jenkins didn't come up.

i.e. using startJenkins.sh (Linux only). Note: On Windows7 Jenkins started as a Windows service.

#!/bin/bash
export JAVA_HOME=/production/jenkinsAKS/java/jdk1.6.0_03
export JENKINS_HOME=/production/jenkinsAKS
export PATH=${JAVA_HOME}/bin:${PATH}
export JENKINS_HTTP_PORT=9040
export JENKINS_AJP13_PORT=9949
now=`date +%Y%m%d_%H%M%S`

echo  $0 begins ${now}
echo "   java-home=${JAVA_HOME}, jenkins-home=${JENKINS_HOME}, path=${PATH}"
java -jar ${JENKINS_HOME}/lib/jenkins.war -XX:MaxPermSize=4096m --logfile=${JENKINS_HOME}/log/jenkins.log${now} --httpPort=${JENKINS_HTTP_PORT} --ajp13Port=${JENKINS_AJP13_PORT} &

Initially I didn't use "-XX:MaxPermSize=4096m" parameter but as soon as I saw the following error message, I tried various values like 128/512/1024,2048,4096m etc, didn't help with the error.

How can I resolve this issue? The same issue came up when I did the same exercise on my Windows desktop machine. Do I need to use less or a limited number of plugins?

Thanks

In my ~/.bash_profile file, I have set the following 3 variables. Note there are other variables in this file as well i.e. JAVA_HOME, ANT_HOME, SONAR_HOME, SONAR_RUNNER_HOME, etc:

export JAVA_OPTS="-XX:MaxPermSize=512m -Xms512m -Xmx1024m"
export GRADLE_OPTS="-XX:MaxPermSize=512m"
export SONAR_RUNNER_OPTS="-Xmx512m -XX:MaxPermSize=512m"

All - working now.

The first export line: will get Jenkins going without PermGen error, the 2nd line will make Gradle going when Jenkins calls Gradle script (via a another wrapper script for ex. .sh/etc), third line makes "sonar-runner" command to work fine (otherwise, I was getting an error for PermGen after "Initialize Hibernate"... line during sonar-runner command's output). You run sonar-runner command in the workspace where you have compiled java, reports related to static code analysis tools (pmd/checkstyle/findbugs) and other code coverage reports (jacoco/cobertura). Workspace should have "sonar-project.properties" file. Look for SonarQube help pages about this file and what all variables it contains for a project.

All those options are documented here: http://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html or here if you are using Java 7: http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html
