BDB error while starting openldap.

Hi,

I am getting the below error while starting openLDAP.

bdb_db_open: alock package is unstable backend_startup_one: bi_db_open failed! (-1) slapd shutdown: initiated ====> bdb_cache_release_all ====> bdb_cache_release_all ====> bdb_cache_release_all slapd destroy: freeing system resources. slapd stopped. connections_destroy: nothing to destroy.

However, if I am using sudo access, I get no error and could successfully start the server and search the DB.

Could anyone please help let me know what the cause for this error is ?

I am using Berkeley DB 4.4.20 OpenLDAP version : 2.3.39

Thanks, Sumith.
