If the importer runs out of heap memory, it will crash either with "java.lang.OutOfMemoryError: GC overhead limit exceeded", which can be suppressed by adding "-XX:-UseGCOverheadLimit" to JAVA_OPTS, or with "java.lang.OutOfMemoryError: Java heap space". You can increase the allocated heap memory and try again, but keep in mind that although no changes were made in the database, the unsuccessfully imported files are still left in the assetstore (see DS-2227).

Disable User Interaction for Cron

If you wish to run any of the following commands from a cron job (or similar), then you may wish to disable all user interaction using the -u (--no-user-interaction) flag. For example, supposing you wanted to perform a full Site Backup (see Exporting Entire Site above) via a cronjob, you could simply run that command passing it the "-u" flage like this:

# Perform a full site backup to AIPs(with user interaction disabled) every Sunday at 1:00AM
# NOTE: Make sure to replace "123456789" with your actual Handle Prefix, and "admin@myu.edu" with your Administrator account email.
