Hi,

Take a look at the Alfresco Installation document at http://wiki.alfresco.com/wiki/Download_Labs.

Edit the line, where JAVA_OPTS is defined in alfresco.sh to something like

export JAVA_OPTS='-Xms128m -Xmx1024m -XX:MaxPermSize=256m -server'

Also take a look at this link about JVM tuning for alfresco http://wiki.alfresco.com/wiki/JVM_Tuning

Thank you so much for responding…..
We have already changed the Java opts you mentioned many times but we are still getting the exact same error. We recently had a successful 2.1 deployed on the same Linux server machine. We know that 3.0 is bigger, but there must be something we are overlooking!

Guess what…..you suggested I check out the "JVM Tuning" section so we did and what we found actually WORKED!

So, thanks a lot and I'm adding the solution below so maybe it will help someone else having an "Out of Memory" problem on a Linux server!

VALUES ADDED TO START UP SCRIPT:

JAVA_OPTS=
-server
-Xss1024K
-Xms1G
-Xmx2G
-XX:MaxPermSize=128M
-XX:NewSize=512m

Thanks again!
