With Sophos Anti-Virus for NetApp Storage Systems, the filer console may display the message "original request is not found" in connection with a request sent to the anti-virus server to scan a file.
The NetApp filer uses a timeout mechanism when it sends a request to the anti-virus server to scan a file. If a request is not answered before timeout occurs, it is removed from the list of requests on the filer. If the anti-virus server then answers the request when it has finished scanning the file, the filer reports there is no request for the answer it has just received.
What to do
This message can be safely ignored.
