The following Alert EMS message might be displayed:
Event Name: secd.dc.out.of.pipe.instances
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 occur 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.
The event will also include the SVM that encountered the failure, the domain controller (DC), pipe on the DC, and the number of retries.
