Solution:-

The Workbench application of Tools and Framework is stored within a Tomcat instance.  Sometimes the Endeca project configuration can become large enough where the maximum heap needs to be increased.  
This can be adjusted the maximum heap size to Tomcat JVM  by editing the -Xmx value. The default value is 1 GB. Change this to -Xmx2048m to specify a 2 GB maximum heap size or higher as per need.

Goto  $ENDECA_TOOLS_ROOT/server/bin/workbench.sh and modify Xmx settingf below.

CATALINA_OPTS="${WB_CATALINA_OPTS} -Xms256m"
CATALINA_OPTS="${CATALINA_OPTS} -Xmx2G"

Note:- Restart Endeca Tools and fFramework after making changes.
