OutOfMemoryError errors

[jaydye]

Hi, we're having consistent problems with OutOfMemoryError when users upload documents.

The Alfresco server is a Windows 2008R2 x64 ESX VM with 16GB RAM, 4 CPU running Alfresco Community v4.0.0 (4003) schema 5025
We also have a 2nd server for the DB.

Presumably the heap size is configurable? What is the recommended size and where do I set it ?

Many thanks, Jay

Here's my env;
$JAVA_OPTS  -Djavax.net.ssl.keyStore=mySrvKeystore -Djavax.net.ssl.keyStorePassword=*secret* -Xms4G -Xmx8G -Xss1024k -XX:MaxPermSize=256m

It may be worth upgrading to 4.2.e before trying to tune 4.0

Thanks for the suggestion - I presumable the newer version has improvements?
How involved is the upgrade from 4.0 to 4.2e with Windows ?
