Why would you have to shut down a server to slapcat it?  Hot slapcatting
has been supported for a long time.
Right, slapcat's man page indicates it's always safe to run against the bdb
backend, but I suspect that's referring more to read concurrency and not
necessarily the generation of a consistent, point-in-time snapshot of the

Consistency is preserved at entry level. If there is consistency needed across several related entry this cannot be guaranteed with pure LDAPv3.

That's not relevant here. Syncrepl guarantees eventual convergence.
