Hello all,

For our application, we are using multipart messages with 4 parts in

For our usage of ZMQ, we would be very pleased if issues
- LIBZMQ-268
- LIBZMQ-283
- LIBZMQ-286
could be fixed before ZMQ 3.1 becomes the stable release. They are
annoying for our cases.
Thank's very much for your work.

Hello all,
I am using ZMQ 3.1 and the PUB-SUB communication pattern.
Is there a way to disable the ZMQ automatic reconnection feature?
I know it exist the socket options RECONNECT_IVL and RECONNECT_IVL_MAX
but according to my knowledge,
they simply allow to delay ZMQ reconnection attempts.

Is there someone in this list also experimenting this problem!
If yes, is there any solution?

switch between the 2 hosts. But as far as I have understood PGM, it is a

Are you aware of some similar cases?

Martin,
I am sorry but I don't understand.
The unit of this ZMQ_RATE is kilobits/seconds.
Therefore 2 means around 20 Mbits/seconds.
My link is 100 Mbits/second. This means that I am using one fifth of the
available bandwidth.
Where is my mistake?

sible that ZMQ layer gives to the OpenPGM layer a
bandwidth value increased by a factor of around 5 % to automatically
have bandwidth available for RDATA
pcakets?
This could make user life easier.
It's just a proposal
Have a nice week-end

Is there any rules regarding compatibility between ZMQ releases (minor
and/or major)?
