Instability With Fusion 9 Rendering Node

Hello forum,

I am currently experiencing instability with deployed Fusion 9 Rendering Nodes. The instability is that ~15% of renders fail when rendering, the vast majority of these with errcode 10. I will attach below a sample set of logs from one of the failing renders. The error indicates that a merge node cannot get a frame input and the failure comes from this. All provided assets are present, as can be indicated by immediately re-running the render in place without making any changes. A similar percentage of the time it will succeed.

We are hoping to increase the stability of our rendering process, so any insights would be appreciated!

Thanks,
Nathan

Any sources provided by media files such as mov or avi instead of frames?

Can you provide your OS and system specs?
