If this is supposed to be a warning that the end user (who hasn't knowingly
set a timeout value) can understand, then I would suggest we might reword it

sure that the user actually wanted (or at least understood the pros/cons of)
a heartbeat in the first place

This looks like debug to me... unless there is something I am missing
