ok, this appears to be user error. Sorry.
i am still curious if this only need be done on replicated masters and not the read-only
replicas or must this be configured on all servers.
Glad to hear it was ok. I
suggest to set 30000 on all servers since the
deletion is replicated to each read only replica and the DB behaves in
the same way.
Thanks,

thanks!

according to the documentation in section 2.5 of the admin guide “Lock Files” by setting
nsslapd-db-locks to 30000. I notice in cn=database,cn=monitor,cn=ldbm
database,cn=plugins,cn=config the attribute nsslapd-db-configured-locks does not change -
it was 10000 before I set it to 30000 and it remains 10000.
