# jive5ab — Troubleshooting

## No VDIF data recorded to disk

**Cause**: The VDIFPacker is not sending to the correct IP/port, or `jive5ab_recording_path`
is not mounted.

**Resolution**: Verify `udp.dest_ip` and `udp.dest_port` in the VDIFPacker configuration
point to the jive5ab container. Check that `jive5ab_recording_path` is defined and the host
path exists.

```bash
docker exec edd_jive5ab ls /data/
```

---

## Field System cannot connect to port 2620

**Cause**: The container is not running, or the port is not reachable from the Field System
host.

**Resolution**: Check container status and verify network routing:

```bash
docker ps | grep jive5ab
docker logs edd_jive5ab
```

---

## Container exits immediately after start

**Cause**: The `jive5ab` binary fails to bind port 2620 (already in use).

**Resolution**: Check for other processes or containers using port 2620 on the host:

```bash
ss -tlnp | grep 2620
```

## Log locations

| Log | Location |
|---|---|
| Container stdout | `docker logs edd_jive5ab` |
| Recordings | `/data/` inside container, mapped to `jive5ab_recording_path` on host |
