#### Why my Open OnDemand JupyterLab/Interactive App Session is stuck and is not starting?
 
The most common reason for this is full `$HOME` directory. You can check the size of the directories in `$HOME` by running `ncdu` on the terminal from the `$HOME` directory.
 
 
Then, please remove any unnecessary data; move data to [$COMMON or $WORK]({{< relref "../handling_data/" >}}); or [back up important data elsewhere]({{< relref "../handling_data/data_storage/preventing_file_loss.md" >}}).
 
If the majority of storage space in `$HOME` is utilized by `conda` environments, please [move the conda environments]({{< relref "../applications/user_software/using_anaconda_package_manager#moving-and-recreating-existing-environment" >}}) or [remove unused conda packages and caches]({{< relref "../applications/user_software/using_anaconda_package_manager#remove-unused-anaconda-packages-and-caches" >}}).
