Hi, I can confirm this is often caused by corrupted Data.fs. Other potential causes are bad rsync transfers.
http://collective-docs.readthedocs.org/en/latest/troubleshooting/exceptions.html#valueerror-non-zero-version-length-versions-aren-t-supported sauna.reload increases your changes of corruption Data.fs as it forcefully restarts Zope instance very often and makes other bad things happen. I suggest you run sauna.reload in new ZEO mode (client + db) in which case the database process stays intact between restarts. -Mikko On Wed, Apr 25, 2012 at 07:56, Andreas Jung <li...@zopyx.com> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > The issue was possibly caused by a regression with the sauna.reload > add-on for Plone...now checking a new version of sauna.reload. > > - -aj > > Andreas Jung wrote: > > I am receiving the following weird error with a fresh Plone 4.2b2 > > sandbox during development tests.
