For an unknown reason, it seems our data.fs got corrupted last night. In the event.log I can see the following: ------ 2008-07-30T22:51:59 ERROR ZODB.Connection Couldn't load state for 0x086540 Traceback (most recent call last): File "C:\PloneExt\Zope\lib\python\ZODB\Connection.py", line 704, in setstate self._setstate(obj) File "C:\PloneExt\Zope\lib\python\ZODB\Connection.py", line 740, in _setstate p, serial = self._storage.load(obj._p_oid, self._version) File "C:\PloneExt\Zope\lib\python\ZODB\FileStorage\FileStorage.py", line 549, in load h = self._read_data_header(pos, oid) File "C:\PloneExt\Zope\lib\python\ZODB\FileStorage\format.py", line 193, in _read_data_header raise CorruptedDataError(oid, s, pos) CorruptedDataError: Error reading oid 0x086540.

Thanks in advance Remy
