Hai Everyone,


We are facing java heap space issue , can any one suggest me how solve this issue,



OS: Redhat linux,

Alfresco Version: Alfresco-Community-5.2 (201707)

Solr version: Solr4

PostgreSQL : 9.4.12

System RAM: 16GB

In Alfresco we increased Maximum heap size as -Xmx8192M

In External Solr4 tomcat : we increased Maximum heap size as -Xmx4096m



1) In Alfresco i am retrieving extra attributes through Active directory with common-ldap-context.xml file. and adding all the users into a group based on the Attributenames for this we developed a jar file.


2) We configured external solr4 in the system for alfresco
