I tried to extract some of the patches from different places and put them into my RPMs. Unfortunately I'm not sure I didn't miss one. I didn't have any db related problem on RedHat with db3 and db4. Of course, the RPMs are using skiplist for mailboxes.db per default, as Rob suggested. I can also suggest XFS as the FS of choice. The only problem is that it is not so well supported by Linux distributions. Simon > > > 2. db3 or db4?
