ALERT

This message occurs when the Windows Domain Controller (DC), while responding to an MSRPC request from Data ONTAP®, returns an error indicating that it ran out of pipe instances in the listening state. This can happen when the requests from Data ONTAP are received by the DC during a timing window when the limited number of listening pipe instance are already allocated to other requests. Such errors received by Data ONTAP might result in longer CIFS/NFS authentication and/or access times, potentially resulting in CIFS/NFS client timeouts.

Contact Microsoft support.
