Hello,

a few days ago I started with zmq and so far most tests I did turned out really 
fine.

I need a pub/sub environment where my subscribers only receive the most recent 
message. Therefore, I set ZMQ_CONLFATE with option_len = 1

This works well for tcp and icp and several subscribers. When I use inproc, 
what so far seemed to be the fastest protocol, only one subscriber can receive 
a message.
By this I mean if my publisher sends a message only the first subscriber can 
receive it. All subs after that won't get any message until a new one is 
broadcasted and this can only be received by one sub, too. When I set 
option_len = 2 this is not a problem any more even I have more than 2 
subscribers.

Is there a solution for this or did I do something wrong?

Thanks in advance,
Barbara
