Local fix

• Disabling the UserTrafficEventListener within the WebSphere
  Commerce configuration file (<instance>.xml/wc-server.xml) will
  help prevent this issue from occurring.
  
      <component
  compClassName="com.ibm.commerce.event.usertraffic.UserTrafficEve
  ntListener"
                 enable="false"
                 name="UserTrafficEventListener">
        <property display="false">
          <start enabled="false" />
        </property>
      </component>
