Kevin,
Is the communication in this case by chance using IPoIB in connected mode?

Hi All,
2018-09-27_09:48:50.923-0500: [E] The TCP connection to IP address
1.2.3.4 some client <c0n509> (socket 442) state is unexpected:
ca_state=1 unacked=3 rto=27008000
Seeing errors like the above and trying to track down the root cause. I
know that at last weeks’ GPFS User Group meeting at ORNL this very error
message was discussed, but I don’t recall the details and the slides
haven’t been posted to the website yet. IIRC, the “rto” is significant …
I’ve Googled, but haven’t gotten any hits, nor have I found anything in
the GPFS 4.2.2 Problem Determination Guide.
Thanks in advance…
