leveldb versio is 1.15.0 plyvel version is 0.9 centos 64bit python2.7

This has nothing to do with Plyvel I think. LevelDB can be used from a single process only. Are you sure you're running only one process that accesses the database? Is you database on a local file system?

my database is on local file system.i running levelDB in webpy+uwsgi.I start three uwsgi process,one mater and two children.when i used uwsgi --reload command,leveldb report the error.

only a single process can access a leveldb database at the same time. (this is unrelated to plyvel.) it looks like your setup does not adhere to this. try with a single process.
