Yes, AFAIK the main problem is not DB, but the combination of DB
and OpenLDAP respectively the way of the usage of DB by OpenLDAP.
Although we tried multiple times to make it as stable as possible during
the last two years (where we observed problems with this), OpenPKG
cannot _guarrantee_ the stability of this combination -- at least not
until we have a regression test which allows to reproduce the problem
consistently.
For instance about 1 year ago the OpenLDAP+DB run fine under FreeBSD
4 and was broken under Solaris. Then we fixed it by using GNU Pth and
some other patches. A few weeks ago it was reported that it now breaks
to some extend (on the replication side) under FreeBSD 5. But everytime
my problem is that I obviously cannot easily fix something if I cannot
deterministically reproduce the problem. So, if you have a reasonably
small regression test ("just install Kolab and run it" is not really
that reasonably small test I would like to use ;-), I can investigate
again.
