As for the KB, it mentions the same stuff in the event route show output, so it’s ok to share here.
Basically, increase your max-tree-connect to 4096.
vserver cifs options modify -vserver exampleSVM -max-same-tree-connect-per-session 4096

Open a case with NetApp.
There is a KB article that they can easily look up that will help. They need to tsearch for "Nblade.cifsSameTreePerSess: Received too many connection requests" and it shoudl come up for them.
Appears to be an internal KB, so I do not feel comfortable sharing.
Exactly your error.

Hi all, been seeing quite a bit of this error recently, and I wondered if anyone had seen this before? It looks like e either the user, or software, is trying to connect to the admin share, but could also just be trying to walk the share tree ,maybe? Full error reads:-
Nblade.cifsSameTreePerSess: Received too many connection requests to the same share from one session: clientIP:port share "ipc$", user "
removed IP and userid.
