Event Name: secd.dc.out.of.pipe.instances Event Description: This message occurs when the Windows Domain Controller (DC), while responding to an MSRPC request from ONTAP, returns an error indicating that it ran out of pipe instances in the listening state. This can occur when the requests from 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 ONTAP might result in longer CIFS/NFS authentication and/or access times, potentially resulting in client timeouts.
