Problem: The SAP Mobile Server services in one of the server nodes cannot start if the domain version has a mismatch. In the server log, there will be an error message containing "Cluster Synchronization failed. Message : Error retrieving sync data from http URL:"
Explanation: This error may be caused by install or uninstalling repeatedly, or receiving an exception during an upgrade.
Workaround: manually update the cluster domain version number under SMP_HOME\Servers\UnwiredServer\Repository\Instance\com\sybase\sup\server\DomainVersion\domain-version.properties, making it the same as the other server node.
