QlikSense Engine CPU Usage

Hello everyone.

We have a smaller Qliksense server installation for demo and internal applications. This is running on an older server with several other applications on it. Its not a producation server and nore of a demo server so that we could test new cpabilaties.

I have now seen for several weeks that the QlikSense Engine service is using 25% CPU (100% of one core. this server has 4 virtual processors) and i cant seem to figure out why. There are no users currently using the system and there are no reloads. So what is using that CPU power? Has anyone seen anything similar?

Please raise a support ticket to investigate more fully. But my first pass thoughts would be this seems related to QLIK-47296, which is in verification but looks to be targeted for 2.0.8. If confirmed then the brief explanation is that an internal thread gets stuck in a wait loop.

Hi Gustav,

can you identify which task is consuming cpu? You could probably restart it then..

It is the Engine Service. If i restart it, the problem goes away for a while. But if i check it again a day later, its back.

Interesting, probably a bug. I noticed some permanent CPU usage of the printing service which is also very suspicious.. I never printed anything.
