If you are doing this on unix, you should consider letting cron handle the daemon portion of this task. This way, all your problems (and a lot of extra code/work) just go away.

Just strip down your script to do one pass at the monitoring, then let it exit. Set up a crontab entry which will run your script at specified intervals. For example, to run your monitoring script every 2 minutes 7x24: 

% crontab -e
