[Fedora-directory-users] High cpu utilizaton by slapd

[Bliss, Aaron]

Found some bad code on a database server; it was querying the ldap
servers to death !!! Thanks everyone for your help.

I think I figured out why, I'm not sure, but the servers are getting
pounded with queries for a particular test user; do you guys have any
idea what is the best way to handle this scenario? Perhaps it would be
best just to delete the test user from the directory and create it
locally?

I'm attempting to turn the logging level back to zero, however I'm
having much difficulty using both the bundled ldapmodify as well as the
ldapmodify that is part of openldap; here is the syntax that I'm using:
/ldapmodify -D "cn=diretory manager" -w mypassword -f /tmp/errors.ldif 

Here is the contents of /tmp/errors.ldif

dn: cn=config
changetype: modify
replace: nsslapd-errorlog-level
nsslapd-errorlog-level: 0

This results in ldap_simple_bind: No such object

Please advise and thanks.

No, not the changelog.
