Created attachment 1422150 [details] sosreport compute-1
I've downloaded the sosreports (from both the Compute node and "UnderCloud"), and I don't see the relevant traceback from either of those sosreports. So there isn't enough info here to tell what's going on. Are you sure you've uploaded the right sosreports?

Without a reproducer I'm going to treat this as a ghost in the machine. Please feel free to reopen if it recurs.
