@Clebert, thanks for the update!
@Caspar, with 2.20 we do see memory issues that I believe are solved in
later versions. But we didn't lose messages the same way we did with
2.24. With 2.20 we're monitoring for AMQ222162 after a crash. We then
recover the old replica's just in case replication failed for some time
because of the memory issues. We have our own duplicate message
detection in our clients, so getting them twice is no prolem for us. But
normally replicaiton works as expected and I guess recovering is not
even needed.
We saw crashes with 2.20 on G1GC and this week also on ZGC, but I know
there were some memory related fixes in later releases. We now prevent
crashes by restarting every few day's, but I would like to go up again
to 2.26. This version worked a lot better for us, but as long as we're
unable to reproduce and fix the missing messages, we're staining on 2.20
for now.
