+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](https://hcc.unl.edu/docs/open_ondemand/managing_and_transferring_files/); or [back up important data elsewhere](https://hcc.unl.edu/docs/handling_data/data_storage/preventing_file_loss/).
+If the majority of storage space in $HOME is utilized by `conda` environments, please [move the conda environments](https://hcc.unl.edu/docs/applications/user_software/using_anaconda_package_manager/#moving-and-recreating-existing-environment) or [remove unused conda packages and caches](https://hcc.unl.edu/docs/applications/user_software/using_anaconda_package_manager/#remove-unused-anaconda-packages-and-caches).
