Broken S3FS HLS

[ingageco]

I've been using this setup for a while, trying to get it ready for production. When generating adaptive HLS via and FFMPEG exec, the HLS ends up broken, streaming OK for a short while, then freezing. It's not a CPU/memory issue, as I've tried it on servers with obscenely high CPU/memory. I've attempted to use DigitalOcean Spaces (where i run the K8s stack), StackPath storage, and Amazon S3 - the issue persists in all 3. I've tried more transcoding, less transcoding, and even letting FFMPEG generate the HLS rather than pushing it into another Nginx-rtmp application. Ive tried switching out s3fs for goofys to no success - nothing solves it.

Any ideas at all what could cause this? Has anyone attempted to use this with Kubernetes at all, with adaptive bitrate HLS generation to S3 success?
