Description of problem: Q: Why is MRG Grid choosing a specific network interface? A: When MRG Grid is run on a node with multiple network interfaces it will attempt to choose which interface it believes is the correct one for communications. If MRG Grid chooses the incorrect interface, the node could fail to communicate with other parts of MRG Grid correctly. It is possible to see which interface MRG Grid is choosing by adding D_HOSTNAME to the logging for the daemon(s) having problems. It is possible to force MRG Grid to use a specific network interface by setting the parameter NETWORK_INTERFACE to the IP address or network interface device that MRG Grid should use.
