Ok, so it looks like a problem with PGM.

I have been using PGM with ZeroMQ 3.1 at a client quite
extensively and it mostly works. It'd be nice to figure out why its not
working for you; it may just be some small detail, OpenPGM can be
somewhat fiddly to get to work.

If you do get a chance do try and investigate with tcpdump to see what
is happening on the network.

As an aside, what Linux kernel and distribution version are you using
exactly? You wrote "Linux 4.1.2" and mention Redhat, but I presume
you're not actually using Redhat 4 which is ancient.
