Hi,
for issues about memory take a look to this https://forums.alfresco.com/en/viewtopic.php?f=9&t=46736&hilit=+memory
Specifically, about configuration look at this http://wiki.alfresco.com/wiki/Full-Text_Search_Configuration

Apparently the earlier parameters did not fix the problem (I thought it was fixed, however in loading another chunk of data today the same issues cropped up).

I have now adjusted the virtual up to 16GB and set the min java to 8GB, max to 16GB and it makes no difference.

This has not been an issue in any previous version of alfresco, any suggestions on how to resolve this issue?

Thanks.

Joe

I'm am not certain that the changes that I'm putting in /opt/alfresco-4.2.b/scripts/setenv.sh are taking effect.
I'm watching the virtuals usage and RAM is never above 13% even whet I've configured it with -Xms8G -Xmx16G

What is the correct way to set the java parameters so that when running "service alfresco start" the parameters will be used?

For anyone else there running into this problem.

You need to modify the file:

/opt/alfresco-4.2.b/tomcat/scripts/ctl.sh

If you try to modify your java settings anywhere else this ctl.sh file will override them when alfresco starts.

I have bumped my -Xms size to -Xms2G and -Xmx to -Xmx4G and i no longer receive out of memory errors.

I'm not a java/tomcat person so if anyone would like to elaborate on these options and suggest a better combination please feel free, but as a quick fix this is working for me for now.

Thanks.

Joe
