Sounds like you need to increase the size of the lock table. See the
note at the bottom of this article.
http://www.openldap.org/faq/data/cache/893.html

The most common occurrence is running out of locks while creating the 
substring index for an attribute with many values, or many long values. 
The longer a value, the more index keys it uses. Each index key gets 
written with its own lock, all under one BDB transaction. Since 
transactions don't release locks until the entire transaction completes, 
updating a single entry can use up a large number of locks.
