Java heap space issue on Solr4

[billydekid]

Hi,

I have a Solr issue during alfresco startup (Alfresco CE 5.2; Solr4).

Following configurations in solrconfig.xml for both workspace and archive Spaces Store has been changed to:

mergeFactor change to 25
ramBufferSizeMB change to 64

as explained here Alfresco Tuning Shortlist – : : blyx.com : : Blog : : Toni de la Fuente : : 

and other sources suggested.

Xmx setting is set to 12GB ([ALFRESCO_DIR]/tomcat/bin/setenv.sh)

JAVA_OPTS="-Xms512M -Xmx12G $JAVA_OPTS " # java-memory-settings

Following are logs from Tomcat's catalina.out which shown heap space issue. What file and configurations should I take care?

Thanks,
