I took a look at this just now. This is a (stupid) interaction between 
syncrepl and syncprov's checkpoint; syncprov has already updated the 
contextCSN so when syncrepl tries to delete the old value it fails because 
syncprov has already deleted it.

The simple workaround for now is to just turn off the syncprov-checkpoint. 
It's unnecessary in the mirror/multimaster config since syncrepl will always 
keep the contextCSN up to date itself.
