The same problem is in your ITS#6126 logs. The entry was received on the
consumer but skipped without any error message.

I see now, the entry was skipped because its CSN was too old. (And that CSN
too old message is only logged with SYNC debug is enabled.) This should be
fixed by the patch for ITS#6346.

It was also suggested that we should only reject mods if their CSN is actually
older than the target entry's CSN. That's still a possibility if the current
patch is insufficient.
