There are definite errors in your cn=config configuration.

a) You have multiple databases numbered "1":
dn: olcDatabase={1}hdb,cn=config
dn: olcDatabase={1}monitor,cn=config

b) Syncprov overlay for accesslog:
dn: olcOverlay={0}syncprov,olcDatabase={1}hdb,cn=config
Remove the checkpoint and sessionlog settings

c) There should be no sessionlog on the primary DB with delta-syncrepl MMR:
dn: olcOverlay={0}syncprov,olcDatabase={2}hdb,cn=config
Remove olcSpSessionlog: 10000

These may not be causing the issue you are seeing, but they should be fixed 
and then the setup retested.  Of particular concern to me is item (a).  I 
would make cn=monitor be olcDatabase {3}.
