It's not very weird. It simply means that the client has lost its
connection to the server.

No statement has been assigned to the dataset at this point. Do you get an
AV message at all? What's the corresponding message in the log (if any)?
specifically, an INET error, or an indication of Guardian trying to restart
the server.

Can you explain what you mean by that? The application is connected to 2
databases? Two programs are connected to one database? One program has 2
connections to one database?

Consider the various reasons why an application that was connected to a
database lost its connection --

Did the server crash? Look in the log file. If it crashed, why? A bad UDF?
Trying to access localhost through terminal services? Host server machine
being overloaded? Too many uncommitted transactions? etc. etc.
