First, make sure your pandorafms server is running:
service pandora_server status
Then, you can manually execute the pandora maintenance script and take a look at what it retrieves, the execution looks like this:
/usr/bin/perl /usr/share/pandora_server/util/pandora_db.pl /etc/pandora/pandora_server.conf
If the execution looks correct, check that it still exists on /etc/cron.hourly/pandora_db, if that's the case, you should have nothing to worry about.
