PermGen Space error when deploying tomcat 7?

Question

I installed tomcat 7 to upgraded my JIRA projeect version from 5.0 to 6. After I place the project folder in tomcat's webapps. I run this localhost:8080/jira after long time running, it throws some error message. Please help us to fix this problem thanks in advance

Solution 1

More helpful solution is to increase values in JAVA_OPTS variable.
Add next line to your Catalina.bat/Catalina.sh file in bin directory

For Windows (Catalina.bat)

set JAVA_OPTS="-Xms1024m -Xmx10246m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"  

For Unix (Catalina.sh)

export JAVA_OPTS="-Xms1024m -Xmx1024m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"  

More solutions you can find in this article

Solution 2

Sometimes after re-deployments the Garbage Collector can't destroy some objects on Tomcat and run out of space. There are many reasons for these case:

• If you use some CRUD-Objects - check if there are all closed after using.
• If your app used other libs - sometimes the Objects from these libs cant also be destroyed, like MysqlConnector, Hibernate/C3p0 or other - try to put these libs on the tomcat/lib folder
  

Check the Tomcat with the "Java VisualVM" and check the permGen after re-deployment.
The default value for the permGen Space are often also very low you can increase them with the following javaVM parameter

 -XX:PermSize=64M -XX:MaxPermSize=256m

You can follow these tutorial

http://www.mkyong.com/tomcat/tomcat-javalangoutofmemoryerror-permgen-space/

UPDATE

other solution maybe found here : what to do with tomcat PermGen space

add -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC to the javaVM options

Solution 3

Tweak the value of the permgen using -XX:PermSize={value} and -XX:MaxPermSize={value} via the JAVA_OPTS variable where 'value' is a string like 256m.

we set the CATALINA_OPTS = -Xms512m -Xmx1024m in Environment variable. And also increase the memory size in tomcat7w which is located in bin folder of tomcat 7. Please help me where I need to change the memory and how to get the result. thanks for the support :)

[user18428]

It's cleaner to set those exports in setenv.sh/.bat

[Maharajan]

After follow the instruction as per the above site also it throws the same error. I am working on windows server. So I changed the values into catalina.bat file. so could u plz give me anyother way to overcome this? Note: I am working on windows server

[Maharajan]

As per your instruction I was change the values in catalina.bat file. so could u plz give me any other way to overcome this?

still i am getting ERROR: Bundle org.springframework.osgi.extender [7] EventDispatcher: Error during dispatch. (java.lang.OutOfMemoryError: PermGen space)

[Zelldon]

have you check the heap and permGen space from the tomcat after redeploy with JavaVisualVm? visualvm.java.net

[Maharajan]

we are working in our local machine

[Zelldon]

no problem... i work also on a local machine and found with java visual vm the problem

[Zelldon]

i have a other solution maybee: -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC found here: stackoverflow.com/questions/10085028/…

[Withheld]

+1 for mentioning catalina.bat.
