Connection Pooling Issue in Webcenter Custom Portal Application

Hi,
 
We have defined our Navigation flow in adfc-config.xml. But when we try to access the page using go-link added in Page Template, Connection count for JDBC Data Source is getting increases for every request. So we are getting Resource Pool error after the Max limit gets crossed. Below is the code:
 
<af:goLink text="#{'Test(adfc-config)'}" id="pt_gil2"
  inlineStyle="font-size:small; color:White;"
  destination="test"
  rendered="#{securityContext.authenticated}"/>
 
We have also tried the use case by adding the Page to Navigation-Model. Even in this case above code doesn't work well. It increases Active Connection Count for the datasource defined in weblogic server.
