slurpd doesn't recognize that the slave is down

["Harms, Hendrik (TOJAQ)" <extern.hendrik.harms@volkswagen.de>]

I'm using openldap-2.0.27 in a master slave configuration on solaris
The replication works. But when the slave ldap is down, the slurpd
did not write anything into the *.rej files. All changes are written into
the slurpd.replog file like those the slave is up. 
How could I find out what changes are sent during the downtime of 
the slave?

Thanks, 
Hendrik
