i'm getting the following error "http-9000-5" java.lang.OutOfMemoryError: PermGen space
org.apache.catalina.core.ApplicationDispatcher invoke SEVERE: Servlet.service() for servlet jsp threw exception java.lang.OutOfMemoryError: PermGen space.
My application using axis2.I increased the heap size 1024mb.But its not working.What would be the problem.Solution please
PermGen and heap size are different from each other.
You need to increase permgen space like this:
-XX:PermSize=256m
-XX:MaxPermSize=256m
add this flags.
Also look at this: explaining-java-lang-outofmemoryerror-permgen-space and this: how-to-deal-with-java-lang-outofmemoryerror-permgen-space-error
Hope this helps.
you need to set something in your tomcat argument
JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m
-XX:MaxPermSize=256m -XX:+DisableExplicitGC"
Note:XX:MaxPermSize=256m
setenv script in your tomcat/bin/ directory. For *nix use a setenv.sh script with export JAVA_OPTS="......" and for Windows use a setenv.bat script with set JAVA_OPTS=......If you're using Tomcat as a Server of Eclipse, go to Server view, then double click on Tomcat, then "Open Launch Configuration", go to Arguments tab, and after setting -Dcatalina.base="" put this
-Xms256m -Xmx512m -XX:MaxPermSize=512m -XX:PermSize=128m
In addition to raising the PermGen size, try enabling permgen garbage collection with
-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled
Try increasing the ram allocation for your JVM. It should help.
Fix for eclipse: You can configure this in eclipse preference as follows
Windows -> Preferences ( on mac its: eclipse ->preferences) Java -> Installed JREs Select the JRE and click on Edit on the default VM arguments field type in --Xms256m -Xmx512m -XX:MaxPermSize=512m -XX:PermSize=128m. (or your memory preference,for 1 gb of ram its 1024) Click on finish or OK.
