[Zope] undo tab at root level hangs forever - db problem?

[simon e. la rosa]

hi,

got one cmf (1.3.1) - plone (1.0.1) site going on a mandrake 9.1 box.

Zope Version: Zope 2.6.1 (source release, python 2.1, linux2), python 
2.1.3, linux2)

Python Version: 2.1.3 (#1, Apr 19 2003, 01:08:28) [GCC 3.2.2 (Mandrake 
Linux 9.1 3.2.2-3mdk)]

System Platform: linux2

behind apache on the same box.

has been working with no worries for about 10 months.

i've been on a 10 days holidays with no internet connection.

today i came back and if i try to go to Control_Panel --> 
Database_Management it hangs with no error message.

if i try to go from the zope root folder to the undo tab it hangs, 
sometimes painting just the first 10 or 20 pixels from the top.

i guess the problem has something to do with the images stored in the db 
  which cannot be rightly retrieved.

i tried to go into the cmf site directly (not through apache) with lynx 
from localhost and it does work (both cmf site and root_folder undo).

maybe somebody (2 other not so savvy people got #root) messed up with 
the unix system date - it was 2 hours in advance. the undo list states 
that the product formulator was installed today (i haven't done any 
activity on zope for the last 2 weeks) - and that product has been 
happily working for the last 3 months.

all in all, a bit of a mess.

i would be grateful if anybody could give me a couple of hints:

1- command line way of browsing the actions list similar to the undo web 
interface, i.e. a log of transactions.

2- command line way to check and run a consistency routine on the zodb. 
i went into the utilities directory, but when i try to run the *.py 
scripts they tell me that the ZOPE object doesn't exist (my encyclopedic 
ignorance pours out from this silly questions...).

thanks,

simon
