We see this for older servers running with newer client versions of Lustre:
2.10.8 servers/2.12.3.93 clients: https://testing.whamcloud.com/test_sets/c6ea7aca-3461-11ea-bb75-52540065bddc

It looks like this started on 27 SEPT 2019 with Lustre 2.12.58.81 clients/2.12.2 servers; https://testing.whamcloud.com/test_sets/6022cbce-e1cf-11e9-add9-52540065bddc.

It looks like the recent cases of this failure are since patch https://review.whamcloud.com/36553 "LU-11367 som: integrate LSOM with lfs find" landed to b2_12 in interop testing with b2_10.

I've pushed patch https://review.whamcloud.com/38021 "LU-13017 tests: clean up sanity 56ra add debugging" that should stop these interop failures.
