[Zope] commit_sub error in add_NetShowLogFile (a ZClass with baseclasses :CatalogAware and File)

[Farrell, Troy]

I have a ZClass NetShowLogFile.  It has baseclasses of CatalogAware and
File.  When I try to add a NetShowLogFile, my python script adds the
file(between 200KB and 3MB), parses the file, executes many SQL methods(two
per line in the file -- average 1000 lines), and
context.REQUEST.RESPONSE.redirect()s to a different page.  The problem is
this:
After it finishes parsing the file and inserting it's contents into the
database, I get a Transaction error:

Error Type: AttributeError
Error Value: commit_sub

Any ideas?  It looks similar to
http://classic.zope.org:8080/Collector/1895/view
and to
http://classic.zope.org:8080/Collector/629/view

It also looks like I may have to move my files to LocalFS objects and
rebuild my ZClasses :(

Thanks for the second time today,
