Frank Budinsky commented on TUSCANY-1132:
-----------------------------------------
Can someone explain why even a "disconnect" is needed? What exactly is the
problem? My preference would be to try to fix this without disconnect or copy,
if possible.

> With or without the patch of TUSCANY-1131 to fix the problem in
