Looks like a corrupt index. I had that a couple times in the past.

It's not removed, just missing from the index.

Because it's still there in the DB.

Reindex you DB. Stop slapd, remove all the indexes and run slapindex. Or 
slapcat/slapadd you DB (that's what I used to do).

You're using an outdated version, upgrade to 2.3.28 and if by chance you're 
using ldbm as your backend, switch to bdb or hdb! Most of these cases I 
remember I had with ldbm, I can't remember any case with bdb (but that 
doesn't mean it can't happen with bdb).
