disk write on old 2.4.9

[richard lucassen <mailinglists@lucassen.org>]

Hello list,

I have an ***old*** Ubuntu-8.04 running 2.4.9. I know, this is old, but
there are no security issues here. This slapd contains a small database
which is modified rarely. OTOH, there are many read operations. The
backend is hdb. As these boxes are running on a CF-disk I'd like to
limit disk writes, but when the database is queried, the backend is
being updated (slapd started at 11:25, read operation at 11:31):

# ls -altr /var/lib/ldap/
total 768
drwxr-xr-x 3 root     root        4096 2013-11-11 20:28 ..

Is there a way to limit these disk writes? I didn't touch the standard
Ubuntu settings, except for the usual settings like SSL.

Richard.
