[galaxy-user] Two Administration questions

Hello, I have two administration-related questions: 1. I have a tool which uses dynamic options from an external file. A cron script updates this file, but the updated data doesn't appear in the tool's list-box until galaxy is restarted. Is there a way to re-load an option file without restarting galaxy? 2. In order to do some routine galaxy maintenance, I need to stop the daemon - Is there way to make sure no jobs are currently running before stopping the daemon? Thanks, Gordon.
