SQL Anywhere 17 - Database server connection limit exceeded

I set up a new SQL Anywhere 17 Database in Sybase Server. I've got a lot of clients that should be able to connect to the Database over ODBC. The ODBC works fine but as soon as the third user tries to connect i get the following message: I've tried

@@max_connections

and got 32'766. Also when I execute the folowing statement I get the following result:

SQL
SELECT 
PROPERTY('ServerEdition') as ServerEdition, 
PROPERTY('IsNetworkServer') as IsNetworkServer, 
PROPERTY('LicenseType') as LicenseType, 
PROPERTY('LicenseCount') as LicenseCount, 
PROPERTY('MaxConnections') as MaxConnections 
FROM dummy

Does anyone have any idea what I can cause this problem?
