The last message was from my test output, it makes no sense anyway. It looks like some QP/CQ initialization problem, but it’s hard to find the exact place at momemnt. I will try Gilles’ patch and see if it’s working for me.
PS: Actually I made the patch from 1.10 series when OOB was removed. Gilles’s patch was made from 1.6.x which worked for me too.

Should be able to restore it. I honestly don’t recall the bug, though :-( If you want to try reviving it, you can add some debug in there (plus turn on the OOB verbosity) and I’m happy to help you figure it out.

I’m working on a virtualization project, and need to run Open MPI on an unikernel OS (most of OFED is missing/unsupported). Actually I’m only focusing on 1.10.2, which still has oob in ompi. Probably it might be possible to make oob work there? Or even for 1.10 branch (as Gilles metioned)? Do you have any clue about the bug in oob back then?

Been a long time - hope you are doing well. I see no way to bring the oob module back now that the BTLs are in the OPAL layer - this is why it was removed as the oob is in ORTE, and thus not accessible from OPAL.

But for some special operating system, where the rdmacm, udcm or ibcm kernel support is missing, oob may still be necessary. I’m curious if it’s possible to bring this module back? How difficult would it be to fix the bug in order to make it work again in 1.10 branch or later? Thanks a lot.
