In reference to the cron error, I posted this a couple days ago: https://groups.google.com/forum/#!searchin/web2py/ross$20peoples$20cron%7Csort:date/web2py/q4qoTTuu6zw/jo-H1LPjWB4J
Also, I should mention that for the stopping problem: It's not just Mac. The previous message with instructions on how to reproduce was done using Ubuntu 10.04.
