High CPU usage white using iLO remote console

chrissilicious — Fri, 01 Oct 2021 08:37:53 GMT

Hey guys,

i noticed that using the HTML5 iLO remote console results in a freeze of the computer where it is usage. While investigating this issue i determine a high CPU usage of 100%. This occurs idependently of browser and iLO versions (iLO 4 and iLO 5 with latest firmware).

Does anyone have the some issue? Maybe already a solution?

Greetings from Germany

Chris

Hi,

I would suggest to reset iLO to the factory default settings.

Refer below Document :-

Hello,

we have the same problem with ilo5 2.42.

CPU goes up to 100% and the Webbrowser gets unavailable and is slow as hell...

Seen on Windows Server 2012R2 and 2019, but NOT on Windows 10 Pro!

Same here, when I use Chrome to launch the iLO connection. Firefox is fine.

I tracked this down to a recent change in Chromium that changes the default renderer from legacy SwiftShader GL to SwANGLE. A workaround until HPE can provide an update is to use the flag --use-gl=swiftshader-webgl

Can someone confirm that is only on Windows Server and not on Win 10?

Has someone raise a support call. If not, I can do!

Hi Ralph,

I have this issue with Windows Server 2016 and 2019. Not tested with other Windows OS versions yet.

Also no case opened until now.

The workaround from aireynol is working for me. But is it only a workaround, not a solution.

The issue is also present in Windows client OS, though as long as you have gpu acceleration available and enabled it works fine. So for example if you have Win 10 in a vm without gpu support then the issue will occur. I did open a support ticket, didn't get any useful response from HPE yet though.

Ok,

I open a support call and gave feedback!

Check out this advisory - https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-a00118787en_us

Although, it states "Chromium-based browser upgrade from v.92.x to v93.x or 94.x.", my browser is already at 95, this did work to resolve the issue, for me.

RESOLUTION

As a workaround, launch the browser with below option as follows:

In Windows Server, right click on the Chrome or Edge shortcut
Click properties
Type --disable-webgl into the target field after the Chrome.exe line (...chrome.exe --disable-webgl)
Click apply

Thanks for sharing.

Has anyone made this work with the edge browser?

The workaround works for me only with the chrome.

HPE Support Case 5359980144.

All I get ist the workaround, and that HPE is still working on this problem!

This dont work for me on Edge Version 96.0.1054.34 (Offizielles Build) (64-Bit) (Windows 2012R2)

Also disable HW accelaration in the setting dont work!

The problem is in Chrome. Edge is built on the same Chromium engine. Just use a different browser.
