Java Heap Space Error

This may be double posted now-but I can’t get to the original post.

I am having a Java Heap Space error

java.lang.OutOfMemoryError: Java heap space.

My heap space is 64mb. My version is 3.2.4. I’m not updated to 3.3 yet. This may be problematic so I can’t do it yet.

I’m sure this is a pretty basic question any help would be greatly appreciated.


I know how to increase the heap on Openfire for Linux. Maybe someone else can help you if you’re using Windows.

Open the server script (/bin/openfire) in a text editor.

Search for a line starting with:

nohup “$app_java_home/bin/java” -server -Dinstall4j.jvmDir="$app_java_home" (…)

Add the parameter -Xmx512m to increase the heap size (512 MB in this example). Like this:

nohup “$app_java_home/bin/java” -Xmx512m -server -Dinstall4j.jvmDir="$app_java_home" (…)


That’s similar to the windows version. The documents finally loaded and searched-they were wonky this morn.

I found out how to do it on openfire as a service-but not as an app. That was odd. However I’ll be upgrading to openfire tomorrow so problem solved.

Thanks for the attempted help wv.
