When setting package limits to the package users, the inheritance principle is applied. It means that:
•If no individual limit is set to a user, then he inherits the limits of the package he belongs to.
•If no limit is set to a package (=0), then the users inherit uid=0 limits.
Limits of the package named “default” (if found in the DB file) will always be ignored and all the users of this package will get uid=0 limits.
