Hi,

Ldap backup was working fine but all of sudden backup were unsuccessful.

Not sure the reason because no changes been done on LDAP and also on machine.

Following below error is seen while doing the backup

---

DATE: 02/21/15 TIME: 17:07:01: Archiving files tar: Removing leading `/' from member names 54e8ad25 mdb_db_open: database "cn=accesslog" cannot be opened, err -30790.

Error -30790 is MDB_READERS_FULL - the configured number of concurrent readers has been reached. You need to raise this limit in your configuration, read the slapd-mdb(5) manpage.

Also consider upgrading to a current release, which includes the error's message text as well as the error code.

Note: the ITS is for actual bug reports - there is nothing in this report that indicates any bug in OpenLDAP software. You should have sent this question to the -technical mailing list. Closing this ITS.

Restore from backup! 54e8ad25 backend_startup_one (type=mdb, suffix="cn=accesslog"): bi_db_open failed! (-30790) slap_startup failed

We are using

# The backup/restore mechanism for openldap/server is based on: # 1. slapcat # 2. config files archive

If you're using cn=config you should just use slapcat for everything.
