Excuse me, where I can read about mapasync limitations on Linux? http://symas.com/mdb/doc/group__mdb__env.html#gab034ed0d8e5938090aef5ee0997f... contains no such info. Seems to me I've missed some important info about configuration.

MAPASYNC uses msync(... MS_ASYNC). Google for this with Linux will give you results like so: http://www.spinics.net/lists/linux-mm/msg71244.html

And in addition - is there way to check DB health status without running slapd?

What health status? The mdb_stat command will return info about the DB.

    No, DB config section is:
    # define MDB parameters
    backendmdb
    databasemdb
    maxsize20000000000
    envflagswritemap mapasync
    # end define


Unfortunately, in Linux mapasync is a no-op. It seems then that your DB is
quite corrupted.
