This is the only code of yours you've shown us, and, sorry, but it's not much to go on. We haven't even seen how you open a database. > But, if I execute only the second test, all works ok...

ZODB comes with a large test suite of its own -- maybe you could study how it opens and closes databases in its own tests. Short of that, try to create a minimal, self-contained, failing test, and post the entire code for that; for what should be obvious reasons, it's hard debug code we can't see. > ZODB3-3.2 That's very old now. ZODB 3.2.8 is the current stable release in the 3.2 line. > python-2.3.3 > Linux Suse 9.1 _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
