A timeout occurred while interacting with sever. Limited information is available - Weblogic

A timeout occurred while interacting with sever. Limited information is available  - Weblogic 

We were getting the error "A timeout occurred while interacting with Server. Limited information is available" while accessing the Server Page from the admin console in clustered weblogic environment and the health of the server is shown as empty but the state is shown as running.
Login to the admin console and accessing the Server page also was taking more time
But the individual servers and the node managers are running fine in all the nodes.

The issue seems to be because of the delay in the communication between the node manager and the managed servers.

Steps to resolve the issue:

• Stop all the managed servers from all the nodes.
• Kill the node managers from all the nodes.
• Stop the Admin server.
• Start the node manager in all the nodes.
• Start the Admin server.
• Start all the managed server.
