Ah, thanks much for the heads up on these additional issues. Perhaps it
would be safest for me to stick with 2.4.41 until a 2.4.45 is officially
released with fixes for both the replication loop and possible fallout from
its fix :). We've been pretty lucky with 2.4.41, knock on bits, it's been
very stable with no issues or problems that I've seen while we've been
running it.
