Hi Robert,

We have been using Xapian/Omega for over a year now and even when we 
started (version 0.6.4 orso, although it was still called 0.4.1-cvs or 
something like that), we didn't run into any such problems. Here is a 
`ls -1sh` of our current working-database:

default-worknew$ ls -1sh
total 13G
4.0k meta
6.2G position_DB
104k position_baseA
104k position_baseB
3.1G postlist_DB
  56k postlist_baseA
  56k postlist_baseB
310M record_DB
8.0k record_baseA
8.0k record_baseB
2.8G termlist_DB
  44k termlist_baseA
  44k termlist_baseB
  67M value_DB
4.0k value_baseA
4.0k value_baseB

As you can see there are three tables which have passed the 2G barrier. 
This is (and has always been) on a Linux system with a 2.4 kernel.

I guess this answers your question.

Best regards,
