Hi. I was fiddling around with my Zope-instance, and decided to Pack the database, I had just deleted a lot of objects and the Data.fs was reported to be about 15MB large; which I knew couldn't be true. Under Control_Panel/Database I pressed the "Pack" button with "days older than" set to '0'. Ahh, the Data.fs became about 500k, that's more like it. For some odd reason, I decided to enter '3' at "days older than" and press "Pack". Dunno why. After I did that it got ugly. Now it reported that the Data.fs was about 400k. Hm, I thought, and checked the var/ directory. It was smaller... strange. I decided to check if the rest of my site was still ok, but it wasn't. When got into localhost/manage every object had their titles changed to 'L'. A bit odd. Very inconvinient. :) Hpmf, I thought while I cleverly scratched my head. I tried to enter one of these 'L'-ified objects, but now it didn't respond at all. I tried to kill the python process, but it had already died. Tried to start it, this is what I got: Traceback (innermost last): File "z2.py", line 436, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "/usr/share/zope/lib/python/Zope/__init__.py", line 130, in ? OFS.Application.initialize(c) File "/usr/share/zope/lib/python/OFS/Application.py", line 171, in initialize app.Control_Panel.initialize_cache() File "/usr/share/zope/lib/python/ZODB/Connection.py", line 391, in setstate p, serial = self._storage.load(oid, self._version) File "/usr/share/zope/lib/python/ZODB/FileStorage.py", line 584, in load try: return self._load(oid, version, self._index, self._file) File "/usr/share/zope/lib/python/ZODB/FileStorage.py", line 560, in _load pos=_index[oid] KeyError: e (actually, it didn't say KeyError: e, but some odd character I don't know how to reproduce.) To fix it I entered the var/ directory, renamed the Data.fs to df-old and renamed the Data.fs.old to Data.fs. Started the Zope-process and everything was fine. Anyone seen this before? It could maybe resemble the bug 1244 (<URL:http://www.zope.org:8080/Collector/1244>), but I don't think so. The strange thing is that it (Data.fs) got smaller when I defined "days older than" to be '3', _after_ having set it to '0'. Versions: Red Hat Linux 6.1 (2.2.12-20) Zope version 2.1.2
