Hi all,

So recently had a show that involved 8 vmix calls and a bunch of media all running on AWS. Everything was absolutely normal until the last two calls joined the event. From that point onward I was getting crazy render time spikes (from sub 15ms to over 500ms). The logs are unhelpful in that they just say that the render time spiked, but not what's causing that spike. I'm now aware of another system (7 calls on AWS) with a similar issue.
Has anyone else experienced this? Any thoughts or ideas as to what might be causing it?

Thanks!

I'm curious if you were doing a peer-to-peer connection (meaning, did you have the "peer-to-peer" button checked in the vmix call window inside of vmix? The reason I asked is that I experienced something similar last weekend. I was able to get about 6 callers on, but ALL of the calls would randomly freeze at the same moment. I confirmed that our WAN connection was completely stable and never went down. We then discovered that we didn't have the proper firewall settings to do a "peer-to-peer" call, so the changes were made yesterday. I'm not quite sure if that did the trick, but I'll know this saturday when we do another stream.

Hi Ryan - did you see any improved results with this?

Hi all,

Just thought I'd wrap this up. The issue is now believed to be linked to the memory leak that was fixed with patch 23.0.0.66.
