My only comment would be, if you want reliable replication, use delta-syncrepl.
Are you saying syncrepl is known to be broken? Or shoddy in general? I find the whole issue that a "top level" of a tree can disappear, but the tree itself still works to be troubling. Perhaps BerkeleyDB broken?
I'm saying that with delta-syncrepl, my replication experience has been reliable. From what I see on the list, people who use normal syncrepl do not have reliable replication.
I did look at delta-syncrepl, but it never ran very well, and seemed quite over complicated for marginal gains. As I understood it, syncrepl always sends entire records, whereas delta-syncrepl can update just the attribute of a record. This did not sound like it would make any difference. Is my understanding incorrect?
With delta-syncrepl, the changes are read directly out of a changes database, in order. The gains are significant.
