The only problem I mentioned was that after having stopped/upgraded the provider and restarted, changes on the directory were not replicated to the consumers (neither to the upgraded one, nor to another one running 2.4.22). I had to restart the consumers for things to start running smoothly again. In the past, in such cases consumers continued to replicate without problems. (But I can remember some cases in the past when this happened again.) I don't know if there are KNOWN circumstances under which the consumers stop picking up provider changes after a restart (of the provider). If so, I would like to know more on the issue, if someone can provide details.
