My definition of 'working fine' is that db_archive showed the log files
starting from the first log (log.0*1) were safe to be removed. As expected,
after removing those files, slapd just worked fine. I didn't try to pull the
plugs out of the wall though. Why db_archive reported the logs can be
removed/archived in my box unlike in Howard's ? that I'm unsure of.
