Cluster cannot be started


I established a scidb database cluster with two computer node. But when I finished installation, and start the cluster using the following command: startall scidb.
(scidb is my scidb cluster name)
The command is just paused. And I checked the log file, it said:


Problem solved! I find that each instance of a node will occpuy an port, in the configure file, the base port is 1239, and form 1239, there are 1240, 1241, and 1242 for other three instances (there are four instances for each node in my configure). So all the ports should be allowed by the firewall. I hope this can help others who meet this problem!
