You don't load the syncprov plugin, so I'm assuming you compiled it in.

You have enough ram to cache 10 million entries?

That's probably checkpointing too often (but I haven't done too much testing
of these settings).

Also note that slapd is quite sensitive to whitespace in slapd.conf. I would
remove any preceeding white space on the above 4 lines.

I'm not sure (I haven't had to debug to this level), but it looks like
sync-repl isn't available (not sure if it should currently be advertised
though ..).

I would check that the suffix has a contextCSN:
$ ldapsearch -LLL -x -b dc=ukbboss,dc=co,dc=uk contextCSN
It should be newer than any entryCSN in your directory. If it isn't, the
consumer will think it is up-to-date.
Also, you may want to search as your syncrepl binddn just to be sure you're
getting what the syncrepl binddn should ...
2.3.11 does sync for me ... but not necessarily if I don't restart the slapd
after some additions (though I may have ommitted the -w to slapadd on the
initial add of some glue entries for my glue-together subordinate
backends ...).

Buchan
