Running out of locks while building db

[pturgyan@umich.edu]

I'm running OpenLDAP 2.1.2 (all standalone system tests passed)
            Berkeley db-4.0.14 bdb transactional backend
            Solaris 2.6

I'm trying to build a database using slapadd,
and I am getting the error:

bdb(dc=umich,dc=edu): Lock table is out of available locks
=> bdb_idl_insert_key: c_get failed: Not enough space (12)
<= key_change 12
<= index_entry_add( 27655, "cn=dm signup,ou=User 
Groups,ou=Groups,dc=umich,dc=ed
u" ) failure
=> bdb_tool_entry_put: index_entry_add failed: Not enough space (12)
=> bdb_tool_entry_put: txn_aborted! Not enough space (12)
slapadd: could not add entry dn="cn=dm signup,ou=User 
Groups,ou=Groups,dc=umich,
dc=edu" (line=873748): txn_aborted! Not enough space (12)

With indexxing enabaled (I'm indexxing about 30 different attributes),
I get the above error after about 27732 entries.  With indexxing
turned off I get to about 65687 entries before I get the lock error.

Also, the Berkeley utility db_archive never lists any log files
as being removable.  I end up with over 250 log files when
building the database with full indexxing.

I didn't see anything in the OpenLDAP archives about this,  nor in
the FAQ.

Here's my conf file:
