I think it looks like this: syncproc_checkpoint modifies the suffix entry, that calls slap_graduate_commit_csn and the csn is removed from be_pending_csn_list. accesslog_response then can't find the CSN there and has nothing to insert into its own pending csn list. Strange that changing the overlay order (accesslog vs. syncprov) doesn't change this behaviour, something I'd expect if the above is the reason this happens=

.

In any case, having the checkpoint modification get its own CSN entry lets the main operation CSN entry persist, which fixes this issue and all operations that need a CSN seem to get it.
