(In reply to Santiago Martinez from comment #43)

Hi Santiago,

Both 172.27.6.129 and 172.27.6.135 are on the same MTU 9000 storage subnet.=
 I
was careful to ensure this for my testing. All of my iperf tests, both fail=
ures
and successes, have been between these 2 IPs on a properly configured MTU 9=
000
vlan which only has hosts on it using MTU 9000.

Also, and FWIW, this storage subnet was configured to MTU 9000 long before =
this
issue ever started occurring. It is a mature, known-good, config.

Best,
Daniel
