You get multiple responses for each ping, the MCM (172.16.4.241)
and what I assume is eth1 on your linux PC (220.127.116.11) both
respond (as they should do). The ping application warns about
received duplicates even if they come from different destinations.
It is harmless, as it was a broadcast ping.

That sounds bad. Unreachable how, the devices crash, become
unresponsive on the network, or something else? And what do you
mean with 'fewer MCMs on the same network', you only mentioned
one MCM above? You haven't accidentally configured the same
address on several MCMs?
