db size problem (4GB monster)

Hi ZMS devs,

we have a big problem with an ZMS site and DB size.

Here are the facts:
- XML-export including binaries has a size of 100 MB
- the ZODB used to have a size of 400-500 MB
- suddenly, a few weeks ago, the size of the ZODB grew to twice the  
size (1 GB)
- that happened another two times, today the DB has a size of 4 GB
- packing ZODB has no effect
- trash is empty
- catalog is not active
- cache is not active
- the site does not contain large binary files or downloads, just  
several files < 1MB
- next strange behavior: exporting different nodes (level 1) produces  
4 GB .zexp files for all single nodes
- exporting as XML and importing it again into a naked site results in  
the error message "The currently logged-in user does not have the Copy  
or Move permission respective to the object zms."
- the only way to reduce the size of the DB is to delete one node by  
the other, pack and if lucky the "monster" gets found: a very time  
consuming procedure.

Did anybody make the same experience?
Does anybody have an idea what might gone wrong?

Thanks a lot for your help.

Best
Joern Paessler
