Environment

Release Automation 6.x

Cause

a ES node is linked to itself as supernode.

Following Query shows some rows with same value for server_id and super_node_id

select * from connected_super_nodes

Resolution

1- Update the properties of "Execution Servers" and remove the links to itself.

 

Example :

In below screenshot one ES is linked to itself. We should remove the link by clicking on the red cross

 

 

 

2- If some NES is not reachable, it is not possible to remove the link using GUI.

 

But it could be deleted using a SQL Query

 

Execute following SQL Query :

 

DELETE FROM connected_super_nodes WHERE server_id=super_node_id

 

to remove the links NES to itself

 

3- Restart Nolio service on NAC
