I have a big problem os latency, when i backup a shared Cifs with Veeam V9.0.1715 , It is very slow.. and never finished .. i must cancel the job ..
This error appear only when Veeam backup the shared CIFS.
I have see it appear this error in logs in Netapp System Manager.
We have created a ticket in Netapp Support also.

Message Name :
Sequence Number :
This message occurs when a CIFS operation times out because the N-blade cannot successfully get a response within 40 seconds. If there are suspensions by Cluster Session Manager (CSM), the N-blade retries the operation, but the CIFS operation times out after the specified time if the N-blade does not get a response.
Check the QoS policy configuration for the target volume. If there are no QoS policies set, check the load on the target volume and check IP connectivity over the cluster interfaces between the two nodes. For assistance, contact NetApp technical support.
