[galaxy-dev] set_user_disk_usage.py as a cron job?

Hello all, I have just encounter a bug with the disk-quota for many users and I run the set_user_disk_usage.py script. It recalculated the disk usage for most of them and now seems that everything is okay. My question is: should I add this script as a cron job or this kind of bugs are just something inusual that happens after upgrading? Best regards, Jose
