Just in case this helps. I generally have cron invoked script produce 
output and make sure the root email is sent to my main inbox. This 
produces handy logs and such. If your running as a user, I'm not sure 
where the output goes, you'd have to check the man. For an hourly script 
this can be way too much, but you can use it to debug as it'll send you 
the error message that's killing the script if that is the case. Sorry 
if you already knew all this.
