# 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.dragen.illumina.com/reference/dragen-application-manager) and [docker.org documentation](https://docs.docker.com/reference/cli/dockerd). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
