Docker says "Connection aborted, Connection reset by peer" - what the hell?

Your container can't reach the internet. This kills 80% of deployments because Docker's networking can eat shit. Spent 4 hours at 3am debugging this exact issue - works fine locally, dies in production. Run `docker exec -it container_name /bin/bash -c "ping 8.8.8.8"` - if it fails, your network bridge is broken.Quick fix: `sudo service docker restart` then delete and recreate the container. If that doesn't work, you're on Ubuntu/Pop!_OS and need to [fix the bridge manually](https://superuser.com/questions/1130898/no-internet-connection-inside-docker-containers).

GPU shows up in nvidia-smi but inference still uses CPU

Welcome to CUDA dependency disaster. You probably have version mismatches between CUDA, cuDNN, and ONNX Runtime. Check your setup:```bashnvidia-smi # Shows CUDA runtime versionpython -c "import torch; print(torch.version.cuda)" # Shows PyTorch CUDA version```If they don't match, you're fucked. Uninstall everything and reinstall with matching versions. Don't mix conda and pip CUDA packages. PyTorch 2.1.0 specifically breaks with CUDA 12.3 - downgrade to 12.2 or upgrade PyTorch to 2.1.1+.

Inference takes 30 seconds the first time, then works fine

SAM and Florence models are 2-4GB each. First run downloads and loads them into memory. This is normal but kills user experience. Solutions:- Use [Dedicated Deployments](https://docs.roboflow.com/roboflow-cli/dedicated-deployments) to keep models warm- Preload models on container startup- Switch to lighter models if you don't actually need SAM's overkill accuracy

"LoadLibrary failed with error 126" on Windows

Your ONNX Runtime can't find CUDA libraries. Install [Visual C++ 2022 Redistributable](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist) and add CUDA bin directories to PATH:```C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.6\binC:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.6\libnvvpWindows PATH limit is 2048 characters - if you hit this, CUDA libraries won't load properly.```

Everything works locally but fails in production

Because your laptop isn't production. Different OS, different network, different everything. I've debugged this nightmare at 2am more times than I want to count.Real gotchas that will ruin your deployment:- **Firewall**: Port 9001 blocked by corporate security- **Memory**: Your MacBook has 32GB, production server has 8GB and it's shared with 6 other containers- **GPU**: IT said "yes we have GPUs" but they're all allocated to the ML training cluster- **Permissions**: Container runs as non-root, can't access `/dev/nvidia0`- **DNS**: Corporate network blocks external model downloads

My model works perfectly in Roboflow UI but gives different results via API

API inference uses different image preprocessing than the web interface. The web UI might resize/crop images differently, affecting results. Download your model and test locally with the exact same image to verify.Also check if you're using different confidence thresholds. The web UI defaults to 0.5, but API calls might use different values.

Inference server randomly crashes after 2-3 hours of use

Memory leak in the model loading code. SAM and Florence models are especially bad for this - they'll slowly eat your VRAM until you're running on fumes. The models stay loaded in GPU memory and gradually leak until you run out of VRAM. **Workaround**: Restart the container every few hours with a cron job. Yeah, it's ugly, but it works. Learned this the hard way after a memory leak took down our quality control line for 3 hours because the inference server died overnight. File a support ticket if you're paying for Enterprise.

Performance tanks after the first few hundred inferences

Model cache pollution. Large models push smaller ones out of GPU memory, forcing reloads. You're seeing the performance hit of constantly swapping models in/out of VRAM. **Fix**: Use dedicated model servers instead of the multi-model inference server. One container per model type.

Docker container works fine, but pod crashes in Kubernetes

Resource limits. Kubernetes might be killing your pod when it tries to allocate GPU memory. Check your pod resource requests and limits: ```yaml resources: requests: nvidia.com/gpu: 1 memory: "8Gi" limits: nvidia.com/gpu: 1 memory: "12Gi" ```

Getting 429 "Too Many Requests" errors on free tier

You hit the rate limit. Free tier gets 1000 API calls per month. After that, you're throttled to 1 request per minute, which kills any real application. **Reality check**: The free tier is for demos, not production. Budget for at least the Growth plan ($299/month) for anything serious.

Model accuracy drops 20% on edge devices compared to cloud

Different hardware acceleration. Cloud inference might use TensorRT optimization while your edge device falls back to CPU or uses different CUDA compute capabilities. Test with identical environments. If accuracy still differs, your edge device might not have enough memory for the full model, triggering automatic precision reduction.

Critical Failure Modes and Solutions

Docker Network Failures

Symptom: "Connection aborted, Connection reset by peer"
Cause: Docker network bridge failure - affects 80% of deployments
Impact: Complete deployment failure, containers cannot reach internet
Solution:

Test: docker exec -it container_name /bin/bash -c "ping 8.8.8.8"
Fix: sudo service docker restart then recreate container
Ubuntu/Pop!_OS: Manual bridge fix required

GPU Configuration Disasters

Symptom: GPU visible in nvidia-smi but inference uses CPU
Root Cause: CUDA/cuDNN/ONNX Runtime version mismatches
Breaking Points:

PyTorch 2.1.0 + CUDA 12.3 = incompatible
Mixed conda/pip CUDA packages = failure
Verification Commands:

nvidia-smi  # CUDA runtime version
python -c "import torch; print(torch.version.cuda)"  # PyTorch CUDA version

Critical Requirements (as of September 2025):

Performance and Resource Requirements

Memory Consumption

Model Type	GPU Memory	Impact
SAM	4-8GB	Large model, memory leak prone

Free Tier: 1000 API calls/month, then 1 request/minute throttling
Reality: Free tier unusable for production
Minimum Production: Growth plan ($299/month)

Memory Leaks

Symptom: Server crashes after 2-3 hours
Cause: SAM/Florence models gradually consume VRAM
Workaround: Cron job container restart every few hours
Long-term: File Enterprise support ticket

Decision Criteria

Cloud vs Edge Deployment

Choose Cloud When:

Reliable high-bandwidth internet available
Centralized processing acceptable
Budget allows dedicated deployments

Choose Edge When:

Low latency critical (<100ms)
Bandwidth constrained environment
Offline operation required
