I am having the same issue and I have been for some time now. I just happened upon this thread and having read through it all, I can relate. I operate two ATEM Mini Extreme ISOs in two separate venues. Both are having the same issue. Both venues are music venues and one is used more than the other and is where I am seeing the issue more often than the other.
Some environmental context about the venue where the issue occurs more:
- Live stream events occur weekly and are approximately 1-3 hours in duration
- Content is streamed to You Tube
- Content is streamed at 1080p, 60fps
- Three PTZ cameras and four Marshall CV506 cameras are used in total
- a PC is used as the 8th input for titles etc via H2R as well as Companion for the Streamdeck XL
- The internet connection is delivered to the venue via fiber optic high speed broadband
- The Internet is provided as a PPPoE connection and offers up to 1000Mbps down and 500Mbps up and it easily achieves around 90% of these maximums (as expected) consistently
- The site router runs RouterOS (Mikrotik) and during the times of the issues there is nothing in the logs or traffic graphs that would explain this issues
- I've also setup my PC that is fitted with very capable hardware (Core i9-12900k CPU and NVIDIA RTX3090 GPU) running OBS connected to the USB-C port of the ATEM Mini Extreme ISO and when the ATEM encoder has the cache issue, the PC running OBS does not!
- The bitrate used on via OBS is much higher than the ATEM and in CBR and never skips a beat the whole time!
- I have yet to packet sniff the setup, but, at this point I think it is reasonable to assume the ATEM is at fault here and other posts in this thread seem to support that.
- When testing with the PC and the ATEM, these two devices are the ONLY devices on the network and they are hardwired via Ethernet directly to the gigabit interfaces on the router. There is no WiFi being used and the router is ONLY doing routing and firewall, no intensive tasks at all and the CPU/Mem usage proves that.
Question: From what I can tell the ATEM Mini Extreme ISO has not had a firmware update since April 2021? Version 8.6.1 is that correct? I'm not experienced in live streaming gear, but 18 months seems like a long time? My expectation is that there should be at least quarterly updates? How are issues in firmware addressed??

I've logged an email for this as I couldn't see how to actually log a support ticket?? It is my first time and my first post in this forum. I'm not holding my breath though having read this thread and seen that it has been going on for some time.
I am now using a capable laptop in both venues to remove the risk, but ultimately this is core and critical functionality that should be working and part of the cost of the pro/iso units. I don't particularly like VBR over CBR, but right now, I'd settle for a stable stream using the inbuilt encoder.
I am quite likely in a position in NZ to return this product to the local retailer that it was bought from and get a 100% refund under the guise that the Vendor has their head in the ground and that the failing component is a core part of the unit, but the problem is finding something in the same feature/price range as it.
