R: slapd process needs a restart
thanks for your email.
We're thinking of upgrading both products, but we would like to know if
we have to consider other things:
- we have developed a client using openldap api: do we have to update
something or just recompile?
- do the actual bdb files are compatible with new openldap and Berkley

I would suggest upgrading both OL and BDB. At the least, upgrade OL to
OL-2.1.30. OL-2.1.23, and many many bugs were fixed between the 2.1.23
release and 2.1.30 release. I'd highly advise moving to OL 2.2.23,
the DOS vulnerability in all OL 2.1 releases & OL 2.2 releases that are
less then 2.2.23.
For BDB, BDB-4.2.52 (plus patches) is a more stable platform than
and has better performance as well, in tests that I did for the OL 2.1
a long long time ago.
