We have slapd running on several servers with read loads of between 50 and 200 requests per second and it runs rock stable. What comes tomind, did your server crash at some point? Have you tried to either do a db_recover on the database files (while slapd is not running of course) or slapcat/slapadd to rebuild the BDB from scratch? I get the feeling your BDB is somehow damaged. - Oliver -- | Oliver Brandmueller http://sysadm.in/ [email protected] | | Ich bin das Internet.
