failing. The command is failing with below error.

---------------------------------------------------------------------------
[root@qe-blade-01 ~]# grep -e nsslapd-cache-autosize
/etc/dirsrv/slapd-qe-blade-01/dse.ldif
nsslapd-cache-autosize: 20


[root@qe-blade-01 ~]# ldapmodify -h 127.0.0.1  -D "cn=Directory Manager" -w

        additional info: nsslapd-cache-autosize can't be modified while the
server is running.

Presently the change is possible only by editing dse.ldif file which will
require stop and start of service.

Where are other parameter like nsslapd-dbcachesize can be changed using
ldapmodify on the run.

Also customers may not agree to stop and start service in production
environment for every change.
