[lustre-discuss] lctl ping issue on 2.7.19

Have a bizarre issue, where I can lctl ping between clients and lctl ping between servers
but cannot ping between a client and a server.
on my server, I see the following error that seems to explain the issue:
Nov 10 09:19:01 mds1 kernel: LNet: 328:0:(o2iblnd_cb.c:2343:kiblnd_passive_connect()) Can't accept conn from 10.55.10.11 at o2ib
(version 12): max_frags 256 too large (32 wanted)
Does anyone have any advice on how to simply resolve this?
I'm running 3.10.0-514.10.2.el7_lustre.x86_64 on the server (centos 7.2 base) and
3.10.0-514.10.2.el7_lustre.x86_64 on the client (centos 7.3 base)
also using built in IB drivers.
