Strange. I've updated the cvs archive and re-run the test (on my win xp
machine). And the crash is still there. Below please find the output prior
to the crash (modified only to remove data that is private to the
environment I'm running it - company name and server name). Can it be that
on your environment the connection is not reused?

Cheers,
