Node not connected to database

Hi,

I have a stado cluster setup on two physical severs with eight nodes (four in each). I am able to create table, load data and query also. But when I restart the coordinator and agent service in cluster and then try to connect from command line I am getting the following error.

"SQLException: ERROR: Node 6 has aborted execution, cause is: Not connected to database: "

The database connectivity is not a issue, I have set trusted connection in pg_hba.conf for all database servers inside the cluster.

Below is my stado.config file.

I am not starting any agent on the master node.
