That's not a rebase problem.  It's apparently a concurrency problem of
sorts.  While pulling up the per-user shared memory region, two or more
processes are trying to set up the same mount points.

This is not supposed to happen.  Only the first process actually
*creating* the per-user shared memory is supposed to create the mount
points.  The OS tells a process if it created or just opened a shared
memory region, but for some reason both processes seem to think they
created the shmem region and one of them then stumbles of the EPERM
condition trying to create the root mount point twice.

I don't have a sugggestion, in fact.  Again, this error condition was
supposed to be impossible, but somehow it isn't in your cluster setup.
