[zeromq-dev] zyre question

[Kalyan Bade]

Hi Pieter,

Thanks for the answer. I think I didn't explain the issue properly. We had
this design, but somehow some "shout" messages are lost. Can you please
help if there is a issue in this approach or am I missing something basic
here?

At time t1 -- Thread 1 starts -- does the following -- zyre_new(),
gossip_bind(well-known-inproc-endpoint), zyre_start(),
zyre_join(well-known-group)
At time t2  -- Thread 2..n starts -- zyre_new(),
gossip_connect(well-known-inproc-endpoint), zyre_start,
zyre_join(well-known-group)

At time t3 -- Thread x sends a "shout" to the multicast group, but it is
not received by thread 1. This is intermittent though.

Are the sequence of steps correct? If the zyre network is not ready at t3,
is there a trigger so that we can query for the info that is lost.

Thanks,
Kalyan
