This is a bug, that has been reported several times
recently.

Your file is probably quite large and Zope
wants to store it piecewise in the ZODB (in
several subtransaction). However, some necessary
object does not have the "commit_sub" method.

Look into the collector, whether the bug is already
recorded. If not, do it.
