# Troubleshooting

## Help

### stopping analysis

Pressing Ctrl+C during a DRAGEN step stops the currently running analysis and might cause an FPGA error. To recover from an FPGA error, shut down and restart the server.

### using a non-root user

CAUTION: Do not run analyses as the root user as it can lead to permissions issues when managing data generated by the software.

### using ssh

When running the analysis software using SSH, Illumina recommends using additional software to prevent unexpected termination of analysis. Illumina recommends `screen` and `tmux`.

### using DAM

The pipeline depends on the DRAGEN Application Manager. For issues related to the DRAGEN Application Manager installation, refer to the DRAGEN Application Manager installation guide.

* Ensure DRAGEN App Manager is running properly.

### using docker

* Ensure Docker is running properly. For docker configuration help, please check the [DRAGEN Application Manager installation guide](https://help.connected.illumina.com/dragen/dragen-v4.4/reference/dragen-application-manager) and [docker.org documentation](https://docs.docker.com/reference/cli/dockerd).
