Also see ITS 8448.
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.
The bug noted in ITS#8460 is not present in 2.4 at all. Quanah is also running experimental backports of features from 2.5 and forgets to mention that sometimes. This particular issue is from 2.5 (and is now fixed in git). Most likely it's the same issue as #8448. You can disregard both of these.

I would note that I've opened up two new ITSes for problems that only occur on systems that have the ITS8432 fix. Still waiting on fixes for those, which is why I haven't pushed the fix into RE24 yet.
ITSes 8460 and 8462.

The fix for #8432 only prevents the redundant mod from being
processed
on a particular node. If other nodes are still accepting the redundant op
then yes,
it will continue to propagate. So yes, you need the patched code on
all
nodes.
Okay, thanks for the clarification. I usually stage updates to avoid a complete outage at any given time. It's interesting though that I had never seen this problem running 2.4.41 until I introduced a 2.4.44
system
into the mix, and then it went away once I reverted that system back to 2.4.41. I wonder why that combination caused it to pop up suddenly.
I'll
have to schedule a downtime window and update them all at once and
see
what happens.
By any chance have you had the time to look at ITS 8444? The reporter says he sees a similar circular replication issue when the memberOf overlay is enabled, which we also use.
Thanks much.
