You can probably ignore it and check it in 6 months or so. You have to find the leak and normally it's a gasket or an o-ring but it depends on where it is. As to what it will take to stop the leak. Some of it could be blowing from someplace else. Best bet here is to try to clean it off and wait and see if it comes back, but from what you describe I wouldn't worry about it.
