Issue

  • MGWD becomes unresponsive for many seconds.  
  • MGWD unresponsive causes Panic
Message: nodewatchdog.svc.rpc.noresp: The mgwd service internal to Data ONTAP that is required for continuing data service
was unavailable. The service failed, but was unsuccessfully restarted.

Description: This message occurs when a service critical to
data access fails to respond to service monitoring and is restarted. Data ONTAP(R) might have experienced a serious error and might
operate in a degraded mode.

Corrective Action: If the message reports that the service has "restarted" then no action is required.
If the status is "not restarted" or "unsuccessfully restarted," then reboot the node using the "system node reboot" command with
the "-dump true" option, and then contact NetApp technical support.
