Hello zope-dev, as a suggestion from another mailing list user i have 
forwarded my current problem to this list. To summarize it seems that due 
to some hard drive corruption my zopedb has been left open with a 
lot of open transactions. When i try to clean the db with fsrecover i get 
numerous version lock errors and the db wont load. I have included my 
email to ZobDB-dev as a more thorought explanation.
