EMS alert reported "Nblade.cifsMaxWatchesPerTree: Received too many Change Notify"
Applies to
- ONTAP 9
- CIFS/SMB
Issue
- An application (such as MOVEit) relies on the CIFS ChangeNotify feature to be automatically alerted when the file system changes (e.g. a file is created)
- However, the application is not being alerted
- EMS log file entries occur similar to:
[Cluster01: kernel: Nblade.cifsMaxWatchesPerTree:error]: Received too many Change Notify requests on one tree: clientIP:portXX.XX.XX.XX.XXXX, directory "vol\share\file\path" on share "vol", vserver: "svm".
