Howard,

I was obliged to remove slapd package on consumer. Then compile in 2.4.24 and
restart. doing the same tests, there was nothing diffferent. provider is still
2.4.23
My test: delete 30000 entries, stop consumer when deleting; start again
consumer when it's finished. Consumer is then out of sync.
You haven't posted your provider config. It appears you're using syncprov-sessionlog. Obviously both ends of this system are vital to solving the puzzle.

I changed the provider to 2.4.24 that makes deletes. Hopefully this one was
built on tar.gz
That makes no difference, after restarting the consumer, it does not delete
extra entries

    Hi Howard,

    We were told to migrate to 2.4.23 sometimes ago, and we did some work to
    update our production servers. Can I try 2.4.24 only on the consumer side?
    It would be a pain to migrate all servers to 2.4.24 without package.

    is this related to the last fixes?

    Fixed slapd syncrepl reuse of presence list (ITS#6707)
    Fixed slapd syncrepl uninitialized return code (ITS#6719)
    Fixed slapd syncrepl variable initialization (ITS#6739)


    Fixed slapd syncrepl refresh to use complete cookie (ITS#6807)

    Thanks

    Dom

            Hello,

            I am testing the replication feature in a multimaster environment
            replicating
            into a single database. As stated before, I added serverid to my
            providers. I
            just have two providers for test purpose.
            I tested mass updates on a provider, stopped my replica during
            updates, then
            start again and it's OK, it updates the entries
            If I do the same for mass deletes. I deleted 40000 entries while
            stopping the
            consumer. My consumer is still with 30000 undeleted entries. I
            left the
            consumer for hours, restarting it twice.
            It seems there is no regular compare between consumer or provider
            in such
            situation. I'll simplify to test in a single provider setup, to
            see if it works.

            All servers are 2.4.23


        Please try your test with 2.4.24 instead.
