Veeam crashes HyperV management console vmms.exe Case #05544282

[DennisH.]

Hello together,

we have a server 2022 (build 20348.1) and Veeam V11.0.1.1261 and as soon as we configure something in the backups jobs, the HyperV management console crashes.

We then have to restart it manually, the following error appears in the event log:

Name of the corrupted application: vmms.exe, version: 10.0.20348.1, timestamp: 0xd5901eb7
Name of the corrupted module: vmms.exe, version: 10.0.20348.1, timestamp: 0xd5901eb7

Berichtskennung: 98a9fa04-75f8-4490-8bae-3224d5506654

Is there anything known about the version or does anyone have an idea what this could be?

Hi Dennis and Welcome to Veeam R&D Forums!

Let's wait for the results of research from our support team. Also, I'd recommend to contact Microsoft support team in parallel and ask them to explain what does exception code 0xc0000409 mean and why it can be thrown from vmms.exe. So far, it's difficult to say how can it be related to backup jobs.

Thanks!
