In terms of potential sources of problems with using Messenger, there are many.
I seem to recall Messenger for a long time (or possibly still, I forget) settling messages without actually setting any delivery state, i.e the bit that indicates the message was accepted (/other). I believe in that case Artemis will not consider it accepted, whereas possibly qpidd did (I dont know/recall). You could run the application with PN_TRACE_FRM=1 env variable set to see the protocol trace and confirm whether that is the case. Another potential source of issue could be its particular 'window' handling behaviour, e.g see some discussion on that in this not too dissimilar thread from a few years ago on the Qpid users list: https://lists.apache.org/thread/95b1gycw8n3h3yc6wcb3h1lgv6ovzfry As that thread also talks to, regardless of the issue I'd really suggest you consider migrating off messenger in your application code, especially if you are already looking at migrating your broker. Messenger has not been actively developed in over a decade, and was being supplanted (but not necessarily directly replaced, especially if this is pure C you are using) by newer APIs before then too due to its many specific nuances and limitations; you won't really find anyone willing or able to give it attention these days.
