Explanation:

A maximum of 518 000 user areas can be defined with a PERMLIMIT specification for a serverdb. This number was exceeded when attempting to create a user or usergroup with PERMLIMIT specification. The number of currently existing user areas with PERMLIMIT specification is thereby irrelevant.

It is not possible to create another user area with a PERMLIMIT specification.
