Hi, Note that there's a new option in libzmq 4.2.5 (still in DRAFT so not available without rebuilding for now) to disable the zero-copy receive that was added in 4.2.0: https://github.com/zeromq/libzmq/blob/master/doc/zmq_ctx_set.txt#L130 I'm not sure in which use case payloads would need to be aligned, but for such programs you'll be able to set it - if you have already encountered issues you can rebuild libzmq (or get the packages from our OBS repos: https://software.opensuse.org/download.html?project=network% 3Amessaging%3Azeromq%3Arelease-draft&package=libzmq3-dev ) and try it out. -- Kind regards, Luca Boccassi
