Hi,

I configured (--enable-slurpd), compiled and installed OpenLDAP 2.2.23
(for SUN Solaris 8)  on three different boxes, where one master pushes
changes to 2 slaves.

All boxes contain just 2 entries (identical). I noticed that I get an
io-wait of more than 50 %, when I slurpd process, although I do not
perform any data changes.


I run my 9 LDAP servers on Solaris 8.  slurpd functions just fine.

Here is the top output from my master:

As you can see, slurpd is 0.00%, and iowait is 0.0%.

I would see if

a) Your slurpd can bind to the replicas
and

b) Your slurpd can actually write to the replicas
