[zeromq-dev] PUB/SUB overload: duplicate messages

[Zoufal Andreas]

Hi,

I'm testing the ZeroMQ library regarding robustness. I let send publishers messages out as fast as possible to force an overload on subscribers side. I would expect less received messages, but what I get is very surprising: I always get the right number of messages, but some (more or less) are duplicated. Is it a bug or can I do something to improve the robustness?

I can zip the demo app and mail it if required.

Kind regards,
Andi
