1) ldbm is deprecated, don't use it.

2) if you insist on using it, get a debug stack trace for the abort

3) note that ldbm is still tested regularly in the 2.3 builds, and no one else 
has reported this occurrence, so there's probably something odd in your 
configuration. Providing your slapd.conf might help.

But the ldbm code has been removed for 2.4; support for it is disappearing fast.
