I'm just guessing here. It would need some serious debugging
to really find out what's going wrong.

In the case of the mxODBC Zope DA this can easily be done by
setting the debug flag to a non-zero value, e.g.

from Products.mxODBCZopeDA import ZopeDA
ZopeDA._debug = 2

(this is an undocumented feature :-)
