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): ------ 2001-11-17T00:51:59 PROBLEM(100) ZODB FS FS21 warn: /local/home/a1142/zope/Zope-2.4.0/var/Data.fs time-stamp reduction at 4995254 ------ 2001-11-17T00:51:59 PROBLEM(100) ZODB FS FS21 warn: /local/home/a1142/zope/Zope-2.4.0/var/Data.fs has invalid status, , at 4995254 ------ 2001-11-17T00:51:59 PANIC(300) ZODB FS FS21 ERROR: /local/home/a1142/zope/Zope-2.4.0/var/Data.fs has invalid transaction header at 4995254 ------ 2001-11-17T00:51:59 PANIC(300) z2 Startup exception Traceback (innermost last): File /local/home/a1142/zope/Zope-2.4.0/z2.py, line 564, in ?

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! --- Francis Potter
