Check the data integrity of the data set. Check the network and end-user application on the client side. It is possible 1) the client did not send the necessary data packets to complete the partial record within the z/OS NFS server extended timeout wait, or before the NFSv4 RPC close had arrived or before the z/OS NFS server shutdown, 2) the client terminated or an application is hung or has terminated, or 3) the client needs to be re-booted or the application needs to be restarted to continue processing the data set if the z/OS NFS server has not shutdown yet. For more information about partial records, see Partial record identification and Symptoms of GFSA824W/GFSA825W messages.
