nvidia-gridd failed to acquire license from DLS server license lease expired throttling

The vGPU guest could not reach its Delegated License Service. NVIDIA vGPU throttles clocks severely when unlicensed, so the symptom users report is "the GPU got slow", not "a license expired". This entry explains how to confirm the cause, apply the fix, and separate it from adjacent mig-vgpu failures.

Symptom

nvidia-gridd failed to acquire license from DLS server license lease expired throttling

Root cause

The vGPU guest could not reach its Delegated License Service. NVIDIA vGPU throttles clocks severely when unlicensed, so the symptom users report is "the GPU got slow", not "a license expired". The decisive evidence is the first log line that precedes "nvidia-gridd failed to acquire license from DLS server license lease expired throttling" and differs from a healthy run.

Recommended fix

check the licensing service in the guest, nvidia-smi -q | grep -A3 "vGPU Software Licensed Product", and systemctl status nvidia-gridd.

How Denpex helps

Denpex investigates nvidia-gridd failed to acquire license from DLS server license lease expired throttling using the evidence you provide or your connected workload collects. Earlier rank, host or application evidence is needed to distinguish an initiating failure from a downstream report.

The literal signature is "nvidia-gridd failed to acquire license from DLS server license lease expired throttling". It is a infrastructure failure associated with NVIDIA MIG, vGPU, and partition scheduling. The line identifies the failing operation or subsystem, while the surrounding evidence decides whether it is the initiating fault or a downstream symptom.

The vGPU guest could not reach its Delegated License Service. NVIDIA vGPU throttles clocks severely when unlicensed, so the symptom users report is "the GPU got slow", not "a license expired". The failure becomes visible at this call site because the operation first requires the missing resource, valid state, healthy peer, or correct result. Earlier log lines and a known-good control carry more causal value than the final wrapper exception.

• The workload stops or loses forward progress after emitting "nvidia-gridd failed to acquire license from DLS server license lease expired throttling".
• A retry on the same configuration reproduces the failure because the causal state has not changed.
• The outer framework exception can hide the rank, node, allocation, or dependency that failed first.
• Increasing timeouts or reducing workload size can suppress the symptom without correcting the cause.

• NVIDIA MIG, vGPU, and partition scheduling
• production-shaped multi-accelerator workloads
• containerized and bare-metal deployments of the same stack

Use this checklist to test the hypothesis against a small reproduction. No single line proves the root cause, so preserve the preceding events and compare one variable at a time.

• ✓Find the first occurrence of "nvidia-gridd failed to acquire license from DLS server license lease expired throttling" and preserve at least 100 lines before it.
• ✓Identify which rank, node, device, or process emitted the first related warning.
• ✓confirm the guest can reach the DLS host and port (7070 by default), this breaks after network policy changes far more often than after license changes. Check the client configuration token has not expired.
• ✓Repeat the same input after the targeted change and require the signature to disappear.
• ✓Resume from no checkpoint action; clocks restore when licensed only after the control passes.

• The vGPU guest could not reach its Delegated License Service. NVIDIA vGPU throttles clocks severely when unlicensed, so the symptom users report is "the GPU got slow", not "a license expired".
• The decisive evidence is the first log line that precedes "nvidia-gridd failed to acquire license from DLS server license lease expired throttling" and differs from a healthy run.
• A nearby failure remains a competing hypothesis until a control separates configuration, capacity, transport, and hardware causes.

Use this text as a lookup key in logs and upstream issue trackers. It is not presented as a captured customer log. Confirm the cause from your own preceding events, versions, configuration and the cited references.

check the licensing service in the guest, nvidia-smi -q | grep -A3 "vGPU Software Licensed Product", and systemctl status nvidia-gridd. This changes the condition in the causal diagnosis instead of hiding the outer exception. The repeated control proves ownership before recovery from no checkpoint action; clocks restore when licensed.

# Preserve evidence before restarting
kubectl describe pod <pod>
kubectl get events --sort-by=.lastTimestamp
kubectl logs <pod> --all-containers

# Find the exact signature in the complete log
rg -n -F -- "nvidia-gridd failed to acquire license from DLS server license lease expired throttling" <log-file>

Adapt the snippet to your framework. The same pattern holds for PyTorch Lightning, Hugging Face Trainer, DeepSpeed, Megatron-LM, and vLLM training wrappers. Where the wrapper exposes a config flag (for examplelr_scheduler_type in Trainer), prefer the flag over the imperative API to keep the schedule declarative and reproducible.
