What to do with OutOfMemory error?

Hi,How much memory should alfresco normally use?I'm running alfresco 4.0 on a computer with 4gb of memory.I created two amps, and a client that interacts with the web service api.When I send a file, small sized (< 1MB), alfresco takes a longe time to process it, and the document library browsing

What are your java memory settings?

Assuming you are only allocating 1 GB - give it more. The "rule of thumb" is that you should be giving Alfresco at least 4GB, so it may struggle to run on your computer.

Well,

I have already java installed on my computer, but alfresco also comes with a java installation, am I correct?

In my java installation, I don't have any parameters about allocating memory, so I assume it is the default.

Then you might want to have a look at:
https://wiki.alfresco.com/wiki/JVM_Tuning

The memory estimations are from quite old versions of Alfresco so you might want to dedicate more memory than indicated. However this wiki page will help you understand the different options you have.

Hi,

I've tried changing setenv.bat, it is like this now:

set JAVA_HOME=D:\Alfresco\java
set JAVA_OPTS=-server -Xss1024K -Xms1G -Xmx2G -XX:MaxPermSize=128M -XX:NewSize=512m‍‍

However, nothing changed.

Shouldn't 2 GB be enough just for 1 user?

Aren't my options correct? Should I edit another file?

I saw the configuration here: http://docs.alfresco.com/4.0/topic/com.alfresco.enterprise.doc/concepts/jvm-tuning.html

Your settings are fine.

What else have you got running? It could be something else on your machine.

I've got another Java installation.

Could this be causing issues?

I've got another tomcat but I don't run both at the same time.

I installed alfresco with the executable, namely https://process.alfresco.com/ccdl/?file=release/community/build-4003/alfresco-community-4.0.d-installer-win-x32.exe
