Excuse me, where I can read about mapasync limitations on Linux?
http://symas.com/mdb/doc/group__mdb__env.html#gab034ed0d8e5938090aef5ee0997=
f7e94contains
no such info. Seems to me I've missed some important info about
configuration.

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