Qlik Sense Server 3.0.1 Hub internal server error

[#1]

We have installed Qlik Sense Server 3.0 and then immediately upgraded it to 3.0.1 and we get this two messages:

With firefox: First it says that there is an internal server error, when we try to refresh the page it gives us "An error occurred: No Engine service is available for the following app: app:_hub", after several refreshes it lets us to connect to hub. If we refresh it while we're in a hub it either refreshes or gives us internal error again.

With chrome: Same as with firefox but you have to refresh like 20-30 times before it will let you into hub.

QMC works perfectly fine with both browsers.

Restarting Qlik Sense Server Dispatcher does nothing.

Any idea which logs should I exactly look into or what may cause these type of errors?

Faced with same problem in one aplication. other application works fine

My steps.

open application

use smart search - goto c:\ProgramData\Qlik\Sense\Apps\Search\ delete all sub folder

reload app, try use  smart search and faced with problem "internal engine error"

QS 3.0.1

Try use FF, Chrome, IE 11 - same behevior

The problem is whit the whole hub not just an app, it has already has occurred on 2 separate Windows Server 2012 machines with clean install. I had to install version 2.2.3 which seems to work just fine, but when I upgrade it to 3.x it throws errors again.

i think it's problem linked with smart search in objects

Will try it next time I will need to install QS, thank you.

Hi Alexander,

Have you able to fix the issue with Smart Search yet?

[korsikov]

nope. Qlik support write "R&D developer has isolated the stack call responsible for this behavior and is working full time to resolve it. Unfortunately, the only workaround at the moment is not to use the search."

Hi Alex,

Have you seen this post https://community.qlik.com/message/1107588#1107588

I’m trying to help one of my clients with this issue. Still not sure where to look. I might try to see what’s in that link sit in their cases as well

I'm experiencing the exact same issue.  Random internal error when searching with QS 3.0.1.  Issue occurs on different OS and browsers so it's not related to the client.

Good news, everyone.

Qlik support team report- problem with smart search fixed in 3.1 .
