永久生成内存不足。 如何增加内存？

Question

I installed youtrack. Begin to adjust. And my message is shown:

"Not enough permanent generation memory. Please, refer to documentation on how to increase it."

I went to the documentation. Sought there, tried to register at startup

exec $JAVA_HOME -Xms512m -Xmx1024m -jar $JAR"youtrack.jar" $PORT >> $LOG 2>&1 &

tried to set parameter.

java -XX:PermSize=1024m -XX:MaxPermSize=1024m -jar /usr/local/youtrack/youtrack.jar 8112

Still does not work. I use Ubuntu Server 10.04

Answer 1

这对我有用：

java -XX:MaxPermSize=150m -Xmx512m -Djava.awt.headless=true -jar youtrack-<version>.jar 8080

Answer 2

JVM flag that controls PermGen size is -XX:MaxPermSize . Try to modify startup script for youtrack like this:

java -XX:MaxPermSize=1024m -Xmx1024m -jar /usr/local/youtrack/youtrack.jar 8112

Although, be advised that this may not work on Windows because Tomcat loves ignoring startup scripts. You may need to specify these JVM flags in Windows service properties window.

Or maybe a little bit fewer than 1024m, not sure you really need that much.
