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.

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