[Zope] Error packing database

[Fabian Schoeck]

Dear list,

when trying to pack my data base, I get the following error:

-------
2009-05-26T18:30:52 ERROR ZODB.DB packing
Traceback (most recent call last):

I searched the web for help, but did not find anything really helpful.
Is this due to some timeout of the web browser? The Data.fs is quite
large (7 GB). Should I rather pack the data base via shell and not using
the ZMI? What is the command to do so?

Thanks,
Fabian
