nblade.cifsmaxopensamefile events






This message occurs when the number of times a user tries to open a file over a TCP connection is exceeded. This request and any further requests to open the same file by the user are denied until some open instances of the file are closed. This typically indicates abnormal application behavior.

Corrective Action

Inspect the application running on the client using this TCP connection. The client might be operating incorrectly due to the 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 the (privilege: advanced) "cifs option modify -max-opens-same-file-per-tree" command.
