High CPU and RAM Consumption

brenests77 — Sat, 16 Nov 2024 19:50:29 GMT

Hi community,

We are currently presenting a performance problem sporadically, which is that the QVS begins to take both RAM and CPU counts gradually until it reaches a critical point where the qvws reloads failed, run or are queued indefinitely.

CPU Consumption

RAM Consumption

The server of the case that I expose has installed QVS, QMC, QDS.
Qikview version: April 2019 SR1. It also has the following hardware features:
RAM: 24 GB
Intel Xeon Gold 2.6 GHz (3 cores)

Have you seen this behavior before?
What corrective measures could be applied to avoid this behavior?

Kind regards,

Hi,

You need to check the size of the qvw files, as is with Qlik, when we use QVD's, and the report/application is run, it expands in the memory and CPU utilization is common.

Please also see the following Article with PDF attachment that explains in much greater detail how the working set limits and CPU utilization occur in the QIX Engine:
