    Description

      Using 2.12.3 servers and clients, we hit this bug once on an OSS, once on a client:

      We're using Mellanox OFED 4.7 on servers / routers / this client (not all clients have been upgraded yet).

      We can provide crash dumps upon request. This seems to be a new problem either with 2.12.3 vs 2.12.0 or with Mellanox OFED 4.7 vs 4.5.

      Thanks!

            Peter, that sounds good to me. We haven't hit this issue since we added the two patches above. Thanks!

            As both the mentioned patches are landed for 2.12.4 can we close out this ticket as a duplicate?

            Thanks Amir! I'll see what we can do to test this patch, at least on the LNet routers first. I'll keep you posted.

            the patch for LU-12441 could be applied as is on b2_12

            Attached is an updated patch for LU-12568.patch which should work on b2_12

            Would we be able to try these two patches out and see if they resolve the problems you're seeing on LU-12906 and LU-12907? I think if the router problem is happening continuously it would be quicker to test these two patches on the routers.

            There are two patches which I think should resolve this issue:

            LU-12568 lnet: Defer rspt cleanup when MD queued for unlink
LU-12441 lnet: Detach rspt when md_threshold is infinite

            LU-12568 fixes a memory corruption which could be leading to both of LU-12906 and LU-12907.

            I can port these back to b2.12. Would you be able to test if they resolve the issue?
