I'm getting this reponse when trying to delete certain trashed material and I get corresponding duplicate ID errors from time to time with ordinary email. I had a business recovering from defective LDAP when I introduced another physical server in the same network - my fault and this is the legacy.

I guess the issue is in the key index in mysql - how do I correct it?

Here is one of the error reports (all essentially the same).
