Is this something that we should be planning to include in 2.12.5? Can you confirm whether there are any negative impacts when receiving this message.</p> <p>Jon</p> <p>I am puzzled as to why you are running 2.13 clients. This is not something tested or expected to work on RHEL 8.1 nor supported to interoperate with 2.10.x servers. I would recommend that you consider switching to a 2.12.x client</p> <p>Peter</p> <p>yes, this is the same issue, though it didn't cause panic and reboot in past. It would be helpful to get corresponding panic info if possible. As for 2.12.5, I think that will be useful to patch it too</p> <p>Close as duplicate of <a href="https://jira.whamcloud.com/browse/LU-13136" title="(layout.c:2121:__req_capsule_get()) @@@ Wrong buffer for field &#39;niobuf_inline&#39; (7 of 7) in format &#39;LDLM_INTENT_OPEN&#39;, 0 vs. 0 (server)" class="issue-link" data-issue-key="LU-13136"><del>LU-13136</del></a>. </p> Related LU-13136 LU-13438 Development Epic/Theme client Rank 1|i00w6f: Rank (Obsolete) 9223372036854775807
