I have been running VMix 26 for about 2 years without issues in one of our studios. We updated to VMix 27 on one of the servers and it has started to crash shortly after connecting to zoom meeting within VMix.
This server runs Windows 10.
Seems to work fine on our other server that runs windows 11, however we have not ran it over time yet. Will test that soon.

We have run full hardware tests on the computers and they are reading fine.

Threadripper 3970 32-core (creator mode)
64 gigs DDR4 ram
Nividia 2080TI GPU
Windows 10

Anyone else experience the same issues?

Thanks
Gav

Make sure you have the very latest vMix 27 installed, if the issue persists please urgently contact support as this is not a known issue:

Thanks for the advice, I have just contacted Vmix support.

Vmix is on latest 27.0.0.69
NDI was on 5.6 when crashing, now on 5.6.1
Windows 10

Event log is EventID 56 with no indication of what caused the crash.

Server ran for years without crashing on Vmix 25 & 26. They are single use servers in the studios
Zero other software or apps installed as they are a one use machine (Vmix)

Only installed apps:
Vmix
NDI
Blackmagic/Magewell capture drivers/software
VLC
Standard windows app (Office etc)

All gaming and supplementary apps uninstalled for stability

Thanks again

So a little update to this thread...

Nothing from Vmix support yet.

Not stated on the initial post is the Vmix server is on location outside of its usual studio. Its in a temporary studio. This studio space has ran this server on Vmix 25/26 for over a year without any issues at all.

When we have Vmix 27 live and connected to zoom, shortly after we activate NDI sends and receives with external machines on the network, Vmix 27 crashes the server.

Whats important to note is that this server has ran streams in this particular studio with exact same hardware setup, IT setup and resource setup for 1+ years on Vmix 25/26 without a single crash running the same NDI paths.

It is now only when integrating Zoom within Vmix 27 that it becomes unstable.
We are currently keeping Vmix 27 on the server, however not connecting to Zoom within Vmix and it is back to full stability.

Stability is essential for us, so we are keeping away from Zoom integration until we see high levels of stability come back.

What is surprising is the lack of reports of instability on these forums, however we have been contacting as many professionals in our industry to get their feedback on 27....and the general reports are it is not stable.

Not a huge deal atm for us, as Vmix without zoom integration is rock solid and is such a fantastic software.

Would love to know if its Windows 10, NDI, Zoom integration and NDI backend link that causes the instability. We can definitely confirm it is not hardware related.

Hi,

We have not received any reports of any stability issues with vMix 27 as of the current version.
There were admittedly some wrinkles early on but they have been all resolved.

Also, unfortunately we have not received any emails from you and I just double checked our junk email filters just in case.

When filling out the support form on our web site, double check the email is correct and then after submitting pay careful attention to what comes up on the next page, as
it may require confirming some additional things before actually sending through.

Regards,

Martin

Would also just like to point out if this is accurate and the entire server is crashing, then this will be a hardware or driver fault unfortunately, and not a fault in vMix.
vMix (or perhaps Zoom) may simply be utilising either the faulty driver or hardware at the time.

You can use the WhoCrashed app after a system crash to track down the culprit:

Hi Martin.

Thanks for the reply.

I emailed a few weeks back after being prompted on this forum to do so.

If you haven't received any stability issues then that points to a conflict with something external to Vmix. Maybe driver issues, NDI possibly?

Its difficult for us as you can see from our description....the only change before crashing, is using Zoom in Vmix.

We spoke with a few people who are using it without any issues since its release. We also spoke with many who have had issues, and obviously not reporting them to Vmix.

Can you tell me if we run Vmix integration, and create, lets say 8 isolated callers 1080P, is this utilising the same network bandwidth as pulling in 8 external x NDI sources 1080P? The only thing we can think of causing the crash is network/NDI overload? and NDI crashing the machine?

Thanks again for the replies Martin, much appreciated

An overloaded machine should never crash, unless something is faulty.

We definitely did not receive an email, so all I can guess is that the support form was not filled out completely on our web site:
https://www.vmix.com/contact-us.aspx

Please try contacting us again, as we can't really diagnose anything without the important diagnostic information contained in the vMix Support Report that you can send
as part of the support email.
