Hi John, In the 2.1.x release stream a shared memory capability was introduced into the PMIx component.
I know nothing about LXC containers, but it looks to me like there's some issue when PMIx tries to create these shared memory segments. I'd check to see if there's something about your container configuration that is preventing the creation of shared memory segments.
