What I want to know is in which situation this error occur? thanks

You started an RDONLY transaction in a thread which already has
one.  Either end the current RDONLY transaction first, or use
MDB_NOTLS to allow multiple RDONLY transactions in a thread.

Or: The lockfile is screwed up. Maybe because you forked the process
or opened the environment in a process where it was already open.

Either way, see lmdb.h for usage restrictions.
