#Distributed Data Management

I'm playing with %Net.DB.Iris and stumbled over a mystery

set##class%Net.DB.DataSource

Entering the above lines (in a terminal session) on my local instance yields the correct answer for:

host = "localhost"
host = the real IP of localhost (i.e. host="192.168...")
host = "10.x.y.dev" customers development system (over a VPN tunnel)

but for

host = "10.x.y.tst" (customers test system) I get an error:
 <THROW>zClassMethodValue+8^%Net.DB.Iris.1 *%Exception.StatusException ERROR #5001: Reentrant request
