[Zope] Corrupted Data.fs alert when compacting

[Gilles Lenfant]

Hi,

My Zope instance (2.6.2) doesn't alert or log anything about ZODB 
corruption at startup or when browsing, but when I try to compact it, I 
got this error:

Error Type: CorruptedError
Error Value: C:\Program 
Files\Zopista_2_6_1\var\Data.fs:9676045:time-stamp reduction: 
0342993b626b50b3 <= 034abe992d2f1aa2

The full traceback is...

Traceback (innermost last):
   Module ZPublisher.Publish, line 98, in publish
   Module ZPublisher.mapply, line 88, in mapply
   Module ZPublisher.Publish, line 39, in call_object

I have tried to run .../lib/ZODB/fsrecover.py utility, but the result is 
worse than the previous problem:

How can I "uncorrupt" that ZODB and compact it again ? Is there another 
solution than exporting root folderishes and importing them in a clean 
new instance ?

Many thanks in advance for your hints.
