You can disable profile data upload (contrary to what was said in previous link posted):
<buildinstaller
IALocation="${ia.dir}"
IAProjectFile="timesten.iap_xml"
BuildWorkdirLocation="build"
failOnError="true"
doNotUploadProfileData="true"/>
</target>

This will disable the connection attempt to the server and should avoid the error.
