A bit more information. The problem still exists with Zope 2.10.3, and occurs with Plone 3.0-beta-1 as well as the earlier alpha.

I've now reproduced it in every environment I've tested in, including:

- Ubuntu 6.10 Server
- FreeBSD 6.1
- Solaris 10
- Fedora Core 6
- Mac OS X 10.4

I certainly understand why you wouldn't want to deal with the Plone 3.0 development stack. The problem is reproducible with the Plone 3.0-alpha-2 release (available at http://plone.org/products/plone/releases/3.0) if that's any help.

Attached is a .tgz archive containing the complete zeo and event logs for an error episode.

What is Plone doing during product init that would cause writes,
beyond those which the "stock" control panel does?  We will need
a reproducible testcase which shows this happening without needing
to install the development version of the Plone 3 stack.

For starters, please upload the compolete event log file from the
instance: your trimmed down version is too trimmed to tell us much.
Perhaps the information there will help us narrow the search.

In a ZEO configuration, when starting a client for the first time -- with no Data.fs in place -- with Plone 3.0 Alpha-2 in the instance Products and instance lib/python, during the plone package inits, an error will occur:

...
  from zope.app.event.objectevent import ObjectEvent
2007-03-20 12:47:24 INFO Plone OpenID packages not installed
2007-03-20 12:47:26 CRITICAL txn.-1210956112 A storage error occurred during the second phase of the two-phase commit.  Resources may be in an inconsistent state.
...

Five then fails to load.

This error does not occur if the Plone 3 Products and packages are not present. Nor does is occur in a stand-alone Zope configuration (i.e., no ZEO).

Restarting the client reliably clears the problem.

Problem reproduced on Ubuntu 6.10, FreeBSD 6.1 and Solaris 10.
