Performance issues and errors when opening apps

During the last 2 weeks, our Qliksense production environment encounters a serious performance issue.

Symptoms:

- In mornings it takes quite a while to open an app. On screen the message "initializing" is displayed for a long time, and then, after a while, it shows "App is opened" for a while.

- The HUB screen shows an error message after a couple of minutes, stating something like "Error has occurred, connection timed out because of inactivity".

- Once the app finally opened, it works as expected (not very slow).

- Our test environment (other server) works fine (no errors, less users, but same amount of data).

- After the qlik services have been restarted, the system works fine again.

- Next morning, the system is slow again, and needs to be restarted all over again.

- Nprinting and Qlik tasks are running without issues.

Anyone has a clue as to where we should look to investigate/solve this issue?

Hi Suzanne,

I think we're now experiencing the same issue as you - every few days it takes ages for all of the apps to open (regardless of size) and only a server restart resolves the issue.

The server RAM seems fine, it never reaches 100%.

Did you get anywhere with resolving your issue?

Thanks

Hazel

Hi Hazel,

We've not resolved this issue yet. Has been like this for over half a year now. We've raised an issue at Qlik, they've requested all kinds of things now. Our partner is taking care of that. When we've found the solution, will let you know! Or maybe you can also raise an issue at Qlik? When multiple persons raise the same thing, maybe the prio can go up?

Grt,
Suzanne

Não sei você, mas a lentidão começou a partir da atualização da maio 2022 para maio 2024 patch 1.

estou tendo reclamações praticamente todos os dias. Para ter ideia, minhas máquinas de engine tem 4TB de RAM (isso mesmo!), CPU 32 cores. Máquina dedicada apenas para o QLIK. 

Ao tentar abrir um determinado app, olhamos para o servidor que não tem consumo de 20% de ram.

Scan de antivírus roda às 6h da manhã e leva 10min. Não queria acreditar, mas estou começando a desconfiar que essa versão está esquisita.
