Seems like that should be the case. TCP is a reliable protocol, it
buffers all data till it acknowledged by receiver and resend when
needed. Switch to the UDP if don't need that reliability.

This does not work either :/
I'm unsing PUB/SUB via tcp.
I have captured the tcp connection with tcpdump and I saw that after I
unplug the cable I get tcp retransmission packets.
May this be more a behaviour of tcp itself than of zmq?

Hi,
Try to set ZMQ_SNDHWM to 1. By the way which transport are you using?

Don't know If I get that right, but even If I set ZMQ_RECONNECT_IV
to "-1" my PUB and SUB Sockets are reconnecting to each other after
I replug the cable

Hello!
Is there a opportunity to tell the publisher not to resend
messages?
I have two stations A and B
A publishes all the time
B receives it
A-PUB 10
B-SUB 10
A-PUB 20
B-SUB 20
A-PUB 30
B-SUB 30
A-PUB 40
B-SUB 40
---unplug cable
A-PUB 50
A-PUB 60
A-PUB 70
---plug cable again
B-SUB 50
B-SUB 60
B-SUB 70
....
B does some routines after it gets those values. But I'm not
interested
in 50 and 60 any more, I just want the 70 after reconnection.
I do Heartbeating so I detect connection lost on my own and I can
request the last value as well. So is this possible to disable the
resend mechanism?
Thx
Florian
