If there is change in DNS and IP address for MDEX/ITL servers, we update those in configuration flies which will not work unless, we restart Endeca HTTP Service.
This is because JAVA caches hostname resolution information and therefore changes will not be picked up/recognized.
So, simple resolution is to restart Endeca HTTP Service on ITL box and MDEX box, this will allow JAVA cache to be refreshed with latest host details.
