The 5 are queried a LOT, the other 2 barely get any traffic at all. All, however, are getting the same traffic that they were getting when I was using previous versions of the LDAP server. The 2 that are barely used I've checked for excessive queries being run at the point when load goes crazy and they are getting the usual minimal load. Also that doesn't explain why it's always 24 hours that it goes haywire. It doesn't matter when I restart the service, it could be restarted at 2am, then in 24 hours it will go crazy IO load. -- Brad -- 389 users mailing list 389-users@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/389-users
