Nblade.cifsSameTreePerSess: Received too many connection requests...

bsnyder27 — Wed, 04 Jun 2025 14:44:07 GMT

I recently noticed our event logs getting a great many of these type of errors. Anyone else come accross this? The -max-same-tree-connect-per-session option is set to default of 4096.

Message Name: Nblade.cifsSameTreePerSess
Event: Nblade.cifsSameTreePerSess: Received too many connection requests to the same share from one session: clientIP:port 10.236.33.15:59607, share "ipc$", user "userxxx".
Corrective Action: Inspect the application using the connection and also monitor the other applications on the client. The client might be operating incorrectly due to a faulty application running on it. Rebooting the client might also be helpful. In some cases, clients are operating as expected but require a higher threshold, which you can set using (privilege: advanced) "cifs option modify -max-same-tree-connect-per-session" command.
Description: This message occurs when the number of connections to the same share allowed per session is exceeded. This request and any further requests to establish another connection to that share are denied until some connections to the share are released. This typically indicates abnormal client behavior.

We have the same error with 8.3.2. While investigating if some customer is doing something bad, we decide to raise the value as workaround.
