ZOPE/Debian crashes on ZODB corruption

Hi All,

I’ve been running zope 2.6.4 (source release, python 2.1., linux2), python 2.2.3, linux2) and python version 2.2.3+ (#1, Feb 25, 2004, 23:29:31) [GCC 3.3.3 (Debian)] in a production environment.

And it’s been twice now that my Data.fs got corrupted then truncated and my site crashed (see error below).

I suspect that it’s a bug on the FileStorage pack implementation (see below).

-----------------------------------debug report from zope.org------------------------------

Fixed a serious bug in the new FileStorage pack implementation. If pack was called on the storage and passed a time earlier than a previous pack time, data could be lost. In other words, if there are any two pack calls, where the time argument passed to the second call was earlier than the first call, data loss could occur. The bug was fixed by causing the second call to raise a StorageError before performing any work.

--------------------------------------------------------------------------------------------------------

Question:

Is the bug fixed on the zope 2.6.4 (source release)?

Any idea on this error “unpack str size does not match format”?

Any idea why Data.fs gets corrupted?

Thanks,

Ramon
