There is also a bug in the 2.1.3 back-bdb/idl.c which can cause it to
return this "no space" error whenever an index slot hits about 65535 IDs.
This bug is fixed in the HEAD.

The whole issue of locks and lock objects is a little suspicious, unless
you're
indexing a very large number of attributes. Otherwise, since slapadd is
single-threaded, there really shouldn't be many simultaneously held locks.
