# DeadlineExceededError: Data service worker timed out after 60000ms

- **ID:** `tensorflow/data-service-timeout`
- **Domain:** tensorflow
- **Category:** network_error
- **Error Code:** `DSE_TIMEOUT`
- **Verification:** ai_generated
- **Fix Rate:** 82%

## Root Cause

The tf.data service dispatcher did not receive a heartbeat from a worker within the deadline, indicating worker unavailability or network partition.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| tensorflow==2.16.1 | active | — | — |
| tensorflow-data-service==0.10.0 | active | — | — |

## Workarounds

1. **Verify worker connectivity and restart the worker process with proper gRPC settings.** (85% success)
   ```
   Verify worker connectivity and restart the worker process with proper gRPC settings.
   ```
2. **Reduce the number of parallel calls in the data pipeline to lower worker load.** (75% success)
   ```
   Reduce the number of parallel calls in the data pipeline to lower worker load.
   ```

## Dead Ends

- **** — Restarting the dispatcher without checking worker health does not fix the root cause of worker timeout. (80% fail)
- **** — Increasing the timeout hides the symptom but the underlying network issue remains. (60% fail)
