The server has attempted to prompt the client scheduler for node node name because a scheduled operation should be started. The server is unable to contact the client by using address type address type, with high-level field high address and low-level field low address.
Server operation continues, but node node name is not prompted to start the scheduled operation. If operations should be started for other nodes, the server will attempt to prompt the client schedulers for these nodes. This error is usually caused by network outages or the client scheduler program not being run on the client node.
Verify that the address type and address are correct for this client. The only valid address type is 1 (for TCP/IP). Make sure that the client scheduler is not using an invalid address, obtained at the time the client scheduler was started, from either the client’s options file or from the command line. Verify that the client scheduler for node node name is running and that the necessary communication links to that scheduler are operational. Firewalls must allow traffic from the server to the client and from the client to the server without the session timing out. Ensure that the DNS configuration is correct.
