A da nije do samog 4D DB servera?
Citat:
Using Multiple Connections and Databases
Using the 4D Open routines, a single client can open multiple connections. The client can connect to several databases at the same time. Each connection corresponds to a different 4D Server process.
With 4D Open, each user can open six concurrent connections (processes) to the same server. After the sixth process has been opened with OP Open connection, an additional user is added to accommodate the six additional connections, and so on.
The maximum number of concurrent users is set by the 4D Server license which you have purchased.
Ako tvoj klijent ima 25 licenci, sasvim je logično da 26-ti korisnik neće moći da se nakači, a ako neki od korisnika otvori više od 6 istovremenih konekcija, on će se računati kao dva, pa će onda izgledati kao da može da se nakači svega 24, ako ima dvoje takvih, ili jedan otvori više od 12 konekcija, izgledaće kao da se nakačilo samo njih 23, itd.
