This thread seems to be a false alarm:
I think the effect was result of two open connections with two different virtuel
machines at one time.
When we test an applicastion it may happen that a DBBrowser-Tool is started. And it
might be possible that this database connection was not closed.
No one of my collegues, who discovered the effect, could definitly exclude that
there was only one open connection.
