Thanks for posting the logs. It looks like the create_list function in
within Trove actually generated the EINVAL error, but there aren't
enough log messages in that path to know why.
Any chance you could apply the patch attached to this email and retry
this scenario (with verbose logging)? I'm hoping for some extra output
after the line that looks like this:
(0x8d4f020) batch_create (prelude sm) state: perm_check (status = 0)
thanks,
-Phil
