An existing connection was forcibly closed by the remote host

[alemio]

Hi,
this post is just to signal this strange error when I'm using Unidac with builder c++ 6.0.

Normally it works fine, but I had suddendly this error:

Project ... raised exception class SocketException with message 'Error on data writing to the connection:
An existing connection was forcibly closed by the remote host.
Socket Error Code: 10054($2746)'. Process stopped. Use Step or Run to continue.

The SQL Server database is inside my computer.
The connection string is
Provider Name=SQL Server;Login Prompt=False;Data Source=.\\sqlexpress;Persist Security Info=True;Port=0
The options are
SQL Server.Provider=prNativeClient
SQL Server.PersistSecurityInfo=True

This is an abstract of dbmonitor

What could have happened?
