Hi,

I have a Tomcat 6 server which I am running through MyEclipse 10. When my app loads as Tomcat starts up I am getting “java.lang.OutOfMemoryError: Java heap space”.

As suggested I went to Window-> Prefernces-> Tomcat 6.x -> and added “-Xmx1024m” to the Optional Program arguments section. But the error kept coming. Then I went to Tomcat install dir and added to catalina.bat file “set CATALINA_OPTS=-Xms256m -Xmx1024m “.
But the error still comes.

Any suggestions?

Thanks,
Jehan

Jehan,

Sorry that you are seeing this issue.

Can you please try these settings by going to Window > Preferences > MyEclipse > Servers > Tomcat > Tomcat 6.x > JDK. In the Optional Java VM Arguments section you can try adding :
-Xmx512M

If you are still seeing issues , Can you please open <MyEclipse installation directory>/myeclipse.ini in any text editor and change the values based on the size of your workspace.
-vmargs
-Xmx512m
-XX:MaxPermSize=384m

If you are still seeing the issue, please try increasing the MaxPermSize and check whether that is working.

Please check this link for more information :

Let us know how it works for you.
