Mstscax.dll on Windows Server 2022

Eric_D · May 14, 2024, 8:03am

Hello,

I have an issue, I have 4 servers, 2 on Windows Server 2019, 2 on Windows Server 2022.
On the 2022, the OpenRPA.RDService stops working after a restart and doesn’t come back (and the HD Robots neither). I have an Error message in the Event Viewer, it seems to be due to a mstscax.dll (version 10.0.20348.2400).
I don’t have the same issue with the 2019 (mstscax.dll, version 10.0.17763.5696).

Does anyone have a workaround, or a solution?

Regards

Eric

Could you please check if there is an event right before or right after, that contains a stack trace ?
this error is a generic dr watson message that is not useful for me

Allan_Zimmermann · May 14, 2024, 9:08am

and if not, then please follow the guide here, on how to create a memory dump

Eric_D · May 14, 2024, 9:16am

The issue is not with the OpenRpa but with the OpenRPA.RDService

please read the link i posted, it explain what to look for in the event log, and if not found, how to enable memory dumps in windows.

Eric_D · May 14, 2024, 12:28pm

Hello,

I’ve done the dump and I have this in the dmp file:

Hello Allan,

Thanks for the feedback, could you provide me your mstscax.dll version? to compare it with mine?

Thanks

Eric

Allan_Zimmermann · May 14, 2024, 1:12pm

damn, somehow i must have hit “edit” instead of reply … Strange.
Sorry about that, anyway, I’ll re-port in my own name here.

It would help a lot if you used details for big chunks of text.

So i asked for the file, but fine you know how to run analyze in windbg, but if you don’t load sos clr is still lacking all the information i need.
But it did reveal this error is a buffer overflow in mstscax and not an error in OpenRPA, so might be better to post this on a windows forum or create a support ticket with microsoft if you have software assurance.

I just spun up a fresh 2022 server, ran windows update and installed hd service.
It works without any issues in my test, both from console and as a service

Eric_D · May 14, 2024, 1:15pm

I’m uploading the dump file, to send it as it is…(takes some times…)

Here is the link to the file:

Allan_Zimmermann · May 14, 2024, 1:20pm

Thanks, but not needed, since we now know, this is local to your install and is not an openrpa issue.

Thanks, i did not know about that service, the .dll files from my test rig is here

Hi Allan,

I’ve made a few tests, it seems that when I have too many HDRobots (above 12) the service seems to have some issues to start the RDP sessions and to simply start by the way…
When I only enable 10 HDRobots, the service seems to be working better…

Allan_Zimmermann · May 14, 2024, 2:55pm

What if you start them delayed ? like one at the time …
Is it a “boot storm” issue ?

Eric_D · May 14, 2024, 2:57pm

It works better… Unfortunately, I can’t afford doing so, If I have a server reboot, the service won’t start, I have to manage with max 10-12 HDRobots…

Allan_Zimmermann · May 14, 2024, 3:45pm

I can add a bigger delay between each startup, so it’s not trying multiple at the same time.
But if your on a virtual machines, it might be better to “spread out the load” anyway ( unless you are restricted by license costs )
