Btw.: I use a "special version" of openldap.
Because of limited index slot of 65535, I changed

in openldap-2.4.33.orig/include/ldap_pvt_thread.h
from
#	define LDAP_PVT_THREAD_STACK_SIZE ( 1 * 1024 * 1024 * sizeof(void *) )
to
#	define LDAP_PVT_THREAD_STACK_SIZE ( 2 * 1024 * 1024 * sizeof(void *) )

and in openldap-2.4.33/servers/slapd/back-bdb/idl.h
from
# define	BDB_IDL_LOGN	16	/* DB_SIZE is 2^16, UM_SIZE is 2^17 */
to
# define	BDB_IDL_LOGN	17	/* DB_SIZE is 2^17, UM_SIZE is 2^18 */

as Howard it recommended
http://www.openldap.org/lists/openldap-technical/201101/msg00095.html

Maybe this could be the problem??

My changes are available under:

Yes, that would significantly increase memory usage. I have only ever done the *second* modification (BDB_IDL_LOGN) to fix the IDL issues. I've run that way for years.
Try dropping the modification to LDAP_PVT_THREAD_STACK_SIZE. It has never been necessary for any of my customers, many of whom have DBs with 6 to 10 million entries.
