I think I faced this same problem last week during a massive load of users
(300K +) using a single ldapadd execution.
My db "exploded" (MDB_MAP_FULL) after about 120K users populated.
The main issue was related to the size of the db than to the actual memory
allocated. It grew up to over 12GB before reaching the limit of my file
system. But with memory-mapped files topics are close, I suppose.

Curious enough, populating the same db from a full syncrepl led the db to
grew to only (more or less) 500MB.

As additional information, this server was part of a 5-node multi-master.
And after the ldapadd the db -size was very different on each of the
servers being part of the cluster.

I cannot share any conf, I'm sorry.
Marco
