A quick follow up to this mail. We are in the midst of isolating this fault and our target of suspicion is our AV box. Virus scanning on the filer was disabled for an extended period of time and the error messages did not appear. Trend has provided a hotfix for us which is being tested. Fellow toasters running Trend version, 5.61.0.1025, Engine version 7.100-1003 beware if you are experiencing similar symptoms and error messages.

Cheers Clarence.

Mark,

Way in the past we have had virus scanning issues and worked closely with Trend to fix them all up. The error's we use to get from that side were CIFS: Virus scanner [scanner] completed scan on [file] but original request was not found. We know quite a bit about that side of things, the ip addresses in the xxx.xxx.xxx.xxx are clients workstations, The clients also have virus scanning enabled but another outsourcing company looks after the desktops. We have sent up packet traces and perfstat's today and hope they do find something.

One of the ones I looked at in more details, after getting the user to log out and then terminating the session for her on the filer, it was still active, She logged back on and opened three apps, yet in open files under hyena she had outlook pst and xls's where she had not opened outlook or a file within excel, and there were multiple instances of these files roughly 150 or so.

Are you running virus scanning? Request type 4 is a close, which is only slow when virus scanning is enabled. Maybe what is happening is that you are copying a huge zip file (for example) and the scan is taking a very long time.

We currently have the following error messages being generated on two of our Filers. There is current a Bug ID for a similar error message but with the Request Type being 5 instead of 4.

We have an open Sev 1 case with NetApp. Has anyone else experienced this particular issue and if so a suggested procedure to follow.

Client issues relating from this problem have been anything from unable to map drives, workstations freezes, slowness to access files/folder/shares.

This has been occurring for the past two days and there have been no filer changes done on the systems for many weeks. Hardware Filer head has had diags run on it which was 100% successful.
