OutOfMemory error:PermGen Space

[press]

java.lang.OutOfMemory: PermGen Space error is coming when I am trying to deploy 3 application war files in JBoss Server and run them simultaneously.In 3 applications Iam using third party framework jar files like spring.jar,acegi.jar,ajax.jar,jasperReports.jar,etc. In each one jar files are configured using User libraries.I am also using jasperreports in 2 applications.Many of the times Iam getting this error when I try to generate jasper report

I have had this problem in the past. I fixed it by addind a PermSize and MaxPermSize to my Java Opts in $JAVA_HOME/bin/run.conf

Also see the wiki reference for more information on this.

<snip - from my run.conf>
# Added the PermSize and MaxPermSize to fix the java.lang.OutOfMemoryError: PermGen space error
# see: http://wiki.jboss.org/wiki/Wiki.jsp?page=OutOfMemoryExceptionWhenRedeploying
JAVA_OPTS="$JAVA_OPTS -XX:NewSize=128m -XX:MaxNewSize=384m -XX:PermSize=128m -XX:MaxPermSize=128m -Xmx512m -Xms512m -XX:+DisableExplicitGC"

HTH.
