QlikView Server goes down

Mon, 26 Jan 2026 18:19:17 GMT

We often have issues with the QlikView Server service. After a reboot of our physical server, we will sometimes see this message after someone tries to open a large QVW and it times out.

When we look at the status of the services, we see that QlikView Server is still running:

Why would we be seeing "No Server" then? The only way we have been able to resolve this is to reboot the physical server again. This often has to be done a few times to get it "right", especially if people are continually trying to open reports immediately after the reboot. Furthermore, when the server comes back up after a reboot, the QlikView Server service never starts up, even though it's Startup Type is Automatic. We always have to start it up manually. This service used to start on its own but has not for at least a year now. I'm not sure if it's related to an upgrade or not.

Users are very frustrated when they can't access their reports. Any help you can provide is greatly appreciated!

Hi,

Have you look at the QVS event log to see if you are running out of memory and the service freezing up? This error you are showing means the webserver can't talk to the QVS server. If the two are not on the same box it would be a network issue.

This is what the event log shows:

We use one server for QlikView (webserver and QVS are on the same box).

Hi John,

General it's better to set the start type for the QlikView services to "Automatic (Delayed Start)".

Some time ago I had a similar problem. The QlikView services could not connect to the server, even though they all run with the same domain user - this caused the same error message.

I could solve my problem with the following steps:

in QMS go to System - Setup.

1. For the QlikView Server on the sheet "Security" enable "Allow admin using name and password".

2. On the sheet "Login" enter the fields with the same user your services are running.

3. Do step 2 for all other QlikView services.

Regards

Christian

Hi,

You will need to look at the QVS event logs for more details.

Hi Shiva,

The service would start without it being license. However, in the QMC it would show as unlicensed. See below

Hi John,

Recently I faced the same issue (when No Server appears on-the-fly) but with other errors in Windows logs. In my case the root cause was out-of-memory which presumably appeared to due .shared files, at least it desappeared once I removed all the .shared files.

I assume that some user(s) was able to built too complex conditions which led to memory leak or uncovered application model issues since "No Server" appeared after QVS memory overloading. QVS service rebooted successfully though, but "No Server" appeared after sometime again and again.

I don't have a proof (except absence of errors in Windows logs), but this is the fact. Please feel free to try this approach (just backup your .shared file before) if you have "Allow Session Collaboration" and "Allow Session Recovery" turned on.

I periodically remove .shared files, maybe it will have a sence to switch off "Allow Session Collaboration" and "Allow Session Recovery". Unfortunatelly.

Best regards,

Maxim
