How is your Alfresco deployed? If you used the install package (i.e. not the ZIP package deploying to your own tomcat), the memory settings are not in the catalina.sh file, assuming that you're using the alfresco.sh script to start Alfresco. If you're using alfresco.sh, then the memory settings are located in the ctl.sh file, which is located in

<ALFRESCO_HOME>/tomcat/scripts‍

. You can also use the "top" command in Linux to see how much memory the Alfresco process is using at the time that you're getting out of memory errors.

Hi Parzgnat,

Thanks for your response. I have for now changed tact and decided not to do a full re-index for now as I m upgrading to version 4.2x and need to find out what other issues I would encounter.

To answer your question I am using a Windows server and have made the changes to Catalina.bat

If you're running Alfresco as a Windows service, you need to modify a registry key to change the JVM heap size. The registry key is HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > Apache Software Foundation > Procrun 2.0 > alfrescoTomcat > Parameters > Java > Options

Hope this helps.
