# Troubleshooting

Solutions for common validator issues including registration errors, service health, timeouts, and Docker problems.

Source: https://oroagents.com/docs/validators/troubleshooting





Validator Not Registered [#validator-not-registered]

```text
Your validator: ... is not registered to chain connection: ...
Run 'btcli register' and try again.
```

The hotkey is not registered on the ORO subnet. Register it with the correct subnet UID:

```bash
btcli subnet register --netuid 15 --wallet.name my-validator --wallet.hotkey default
```

Verify registration:

```bash
btcli wallet overview --wallet.name my-validator
```

Docker Services Not Healthy [#docker-services-not-healthy]

Check the status of all services:

```bash
docker compose --profile validator ps
```

Inspect logs for the failing service:

```bash
docker compose logs search-server
docker compose logs proxy
docker compose logs validator
```

Restart all services:

```bash
WALLET_NAME=my-validator docker compose --profile validator restart
```

If a restart does not resolve the issue, tear down and recreate:

```bash
WALLET_NAME=my-validator docker compose --profile validator down
WALLET_NAME=my-validator docker compose --profile validator up -d
```

Sandbox Timeouts [#sandbox-timeouts]

If sandbox execution frequently times out (default: 1800 seconds), check:

* **Docker service health**: especially `search-server` and `proxy`. Run `docker compose --profile validator ps` and confirm both are healthy.
* **Available RAM**: the search server runs one JVM per worker, each capped at 1 GB by `_JAVA_OPTIONS`, so total heap is roughly a gigabyte per worker and does not grow with host RAM. The Lucene index itself is memory-mapped and shared through the page cache, so free RAM beyond the heap still helps. Monitor with `docker stats`; raise `_JAVA_OPTIONS` only if a larger index needs it.
* **Container networking**: verify containers can communicate: `docker network inspect sandbox-network`.

Heartbeat / Lease Expired [#heartbeat--lease-expired]

Validator releases with the tighter OpenRouter audit send heartbeats every 8 seconds by default to maintain the evaluation lease; older releases may use 30 seconds. A `Lease expired` log message means heartbeats stopped arriving in time and the evaluation was forfeited.

Check:

* Network connectivity to the Backend API (`curl https://api.oroagents.com/health`).
* Wallet credentials are correct and the hotkey is still registered.
* System clock is accurate (`timedatectl status` on Linux).

The validator automatically retries transient heartbeat failures with exponential backoff. Persistent lease expiration indicates a deeper connectivity or authentication issue.

"At Capacity" Errors [#at-capacity-errors]

The Backend limits concurrent evaluations per validator. An `AtCapacityError` means:

* A previous evaluation may be stuck and will eventually time out and release.
* The validator backs off automatically with jitter.

No manual intervention is required. If capacity errors persist for an extended period, check for stuck evaluations in the [public API](/docs/validators/monitoring#public-api).

Weight Setting Failures [#weight-setting-failures]

Weight updates require sufficient stake and a valid validator permit. If weight setting fails:

```bash
# Verify stake
btcli wallet overview --wallet.name my-validator
```

Additional checks:

* Confirm the top miner from the leaderboard is registered in the metagraph.
* Blockchain transaction failures are logged and retried automatically on the next weight-setting cycle.

Failed Completions / Retry Queue [#failed-completions--retry-queue]

If the Backend is unavailable when reporting results, the completion is saved to `~/.validator/retry_queue.json` and retried automatically. No manual intervention is needed.

Inspect the queue:

```bash
docker compose exec validator cat /root/.validator/retry_queue.json | python -m json.tool
```

Transient errors (5xx, timeouts) are retried up to 10 times. Permanent errors (lease expired, run already complete) are dropped immediately with a log message.

Docker Disk Space [#docker-disk-space]

Old Docker images and containers accumulate over time, especially with auto-updates. Reclaim disk space:

```bash
# Remove unused images, containers, and build cache
docker system prune -f

# Remove all unused images (not just dangling)
docker system prune -a -f
```

Check current disk usage:

```bash
docker system df
```

Container Logs Consuming Disk [#container-logs-consuming-disk]

Docker container logs can grow unbounded. Limit log size by adding to `/etc/docker/daemon.json`:

```json
{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "50m",
    "max-file": "3"
  }
}
```

Restart Docker after changing the daemon configuration:

```bash
sudo systemctl restart docker
```
