Excuse me, where I can read about mapasync limitations on Linux?
http://symas.com/mdb/doc/group__mdb__env.html#gab034ed0d8e5938090aef5ee09...
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.
