[Zope] Zope-2.5.0 stopped starting up

[Daniel Mahler]

Hi,

A Zope server that has been serving us faithfully
for many months has stopped restarting.
When it was brought down,
Data.fs was hitting the Linux 2G file limit,
but Zope was still operating correctly,
but was refusing zwiki updates.
I brought it down so I could back up Data.fs
in a consistent state.
When I try to bring it back up I get a continuous stream of error
messages:

As far as I know nothing was done to the installation,
and it used to work just fine.
Any ideas ?!?

thanks
