[zeromq-dev] subscriber stopped receiving messages from XPUB socket

hi there,

I have multiple (5-10) subscribers subscribing to the same topic published by one publisher. They are connected via a XSUB-XPUB proxy. All the subscribers are always up and the publisher may come and go at times. I have noticed that at times, after the publisher is restarted, one of the subscribers might stop receiving any messages at all. It's not a slow-joiner kind of issue because the publisher continues to publish message every second and that subscriber may not get any messages at all forever, whereas other subscribers are getting messages at the same time. I also verified that the subscriber is waiting for messages (it's calling the receive function.) and if I restart the subscriber, it will get messages again.

Could someone enlighten me what I may be doing wrong? Is there any thing I should be looking into?

Thanks in advance.
