thanks. I am using 2.4.23
sudo /opt/openldap/libexec/slapd -V
@(#) $OpenLDAP: slapd 2.4.23 (Mar 9 2011 11:39:07) $
I understand that delta-syncrepl will significantly reduce traffic but
that should not be the problem here. Also we have mirror mode turned
on and I read "Note: Delta-syncrepl is not yet supported with
MirrorMode."

a) Always note the version of OpenLDAP you are using
b) Use delta-syncrepl

a) Use a current release. That would be 2.4.33.
b) Delta-syncrepl supports MMR in current releases
c) The reason I suggest delta-syncrepl is because syncrepl is known to be
problematic, particularly with MMR. If you want reliable replication, use
delta-syncrepl.
