Any more thoughts on this? I'm considering a rollback to Gluster 3.4 as I never had these issues and this is keeping me awake at night.

Th qemu log is also the client log. The client was configured for info notices only; I've since turned it up to debug level in case I can get more but I don't remember the client log being that interesting.
