Files get corrupt when save to disc

stabben23 — Mon, 26 Jan 2026 18:19:17 GMT

Hi,

This problem has bother me for over 1 year now. We having problem when files is distribute to the fileserver. The files gets corrupt almost every day, not all just one or two. Its not the same files, but most frequent is the big sized files. Whats happens is that the file dont save the whole file to the disc, around 50-95% of the filesize is saved and then the file is corrupt and cant be opened.

I'll think this is some network issue and not a qlikview problem. Because the Publisher server and the fileserver is not on the same machine.

Here is the last part of the logfile:

Hi,

we have our fileshare on a Windows based NAS, could this be the problem? The QVS and Publisher is on separated servers.

It sounds that the network or the file-system caused these errors. I think you will need to look into the log-files from qv server/publisher and from the windows OS. Maybe there isn't enough cpu/ram-ressources at any time and/or some services like windows shadow copy or firewall/anti-virus are involved. Another reason could be corrupted hardware by ram or disk.

I have a feeling that QlikView does not formally support NAS.

Yes, Thats what I have read here on the community, but the "experts" does not agree with each other in this question.

What happens when you manually copy a very big file from the Publisher machine to the (NAS) File Server? Does the network experience hickups?

Is it just me, or does the log file you posted in reality document a reload failure due to a missing service account from the Section Access table?

I have too often seen NAS set up badly and causing problems. Not have having a TOE (TCP/IP offload Engine) enabled NIC can have bad consequences.

Hi Peter, that is the test we have done, unfortunately is this test ok, we have only test a few times.

Re: Files get corrupt when save to disc

stabben23 — Tue, 28 Apr 2015 11:42:55 GMT

There is no Section Access on the document. I can see Section Access in almost all logfiles when somethings goes wrong.

Thanks Bill,

This is over my knowledge, the whole network is outsourced and really not my area. So I will try to give them some advice where they should have a look.

Hi,

The post about the NAS is correct in that it isn't supported. However, to see if that is the issue, move your root folder back to the local machine and see if your still have the issue.

Hi Bill,

does this rule apply to just the Document Root or to all Qlik files? IIRC some official Qlik training/examination program imposed the storage of configuration and distribution files on shared storage in a Qlik clustered environment, and I don't see why this is suddenly invalid...

The Server Ref manual (for SR10) brings confusing information as well, as on the one hand it explicitly talks about a NAS, and on the other hand it states that only SAN-devices are supported...

Best,

Peter

It isn't so much the NAS as the File system that it uses. Qlik require a Windows based NAS. See the attached. It is a little old, but it might help you.

Very useful. Thanks Bill.

Hi,

this is definitely a NAS problem, we will a soon as possible move all files from the fileshare back to the disk on qlikview server. Just wait for a larger disc.
