it works for ours, are you sure there is a mysql process going on when you are checking? they clear out after a period of time, so you might just be checking when no one is using a database?
if you haven't already, install some script that requires a database, have it call the database.. check webhostmanager right away to see if it logs it. all i can think of on how to check if it really is bust for you.
btw, we are running 4.0.0-STABLE_64, what version/build of cpanel are you running?
