        Logging
            is set as “nslapd-errorlog-level” is set to “8200” – not
            sure where I found that number at, the wiki shows 8192. What
            should I be using or just capture everything?
      
    
    See http://directory.fedoraproject.org/wiki/FAQ#Troubleshooting for
    an explanation of log levels.

    
    Let's look at the core stack trace first.
