Hi everyone,
I'm an experienced Zope user/developer and have never seen anything like this. It appears data.fs is corrupted. Here's the message I get when attempting to start Zope (it's version 2.4.0 on solaris):

Here's the story. I use WebDAV to edit ZPT documents, but had never done so on this particular installation. I changed the start file to open a WebDAV port, and it seemed to work. I was able to browse, edit, and save ZPT's into the database via WebDAV. Meanwhile I had a browser open, operating in a Version. I was curious to see if there's anyway to work in a Version via WebDAV (meaning a Zope Version). Doesn't seem like there is.
After the WebDAV save I started getting cryptic traceback/error messages in the browser. (Sorry I didn't record the messages, they were errors about type conversion. One of them was about trying to convert a longint, and another one made specific references to dates.) Those errors appeared whenever I hit the "Undo" tab on any object in the database.
So I stopped Zope and this error comes up when I try to restart.
Has anyone experienced this problem?
How can I prevent it in the future?
Is there any way to recover the data in Data.fs?
Thanks!
