Found this one: https://github.com/zeromq/libzmq/issues/2009
Is it still not fixed? According to github it needs stacktraces. Should
I post mine there?

Hi all,
when I try to send large messages (~65kB) via UDP Multicast (per draft

Is it known, that the draft API has Problems with large message sizes?
What does the assertion in line epoll.cpp:113 actually check and what
could be the reason to make it fail?
Do you need a MWE in order to investigate it? I probably can create a
simple main, that reproduces this error.
Last remark (not 100% sure about this): If I reduce the message size
to ~2kB, it takes several of these message (~254) to get this error,
but the number of messages seems to be always the same.
Greetings
Stephan
