Symptoms</h2> <p>The <code>clw-gpu-timeout</code> error manifests when OpenClaw fails to receive a response from a GPU device within the expected time window. This error typically surfaces during compute-intensive operations, workload scheduling, or device enumeration phases.</p> <p><strong>Primary symptoms include:</strong></p> <ul> <li>Error message <code>clw-gpu-timeout</code> displayed in terminal output or application logs</li> <li>Jobs stuck in <code>PENDING</code> or <code>SCHEDULED</code> state indefinitely</li> <li>Partial cluster initialization where some GPUs are accessible but others are not</li> <li>Timeout errors occurring during CUDA kernel execution or memory transfers</li> <li>Inconsistent behavior where the same workload may succeed or fail depending on cluster load</li> </ul> <p><strong>Typical error output:</strong></p>
