It looks like this is identified and solved, I'll test on a new version of XO next week at some point, but I just wanted to confirm that I've been seeing what appears to be the same problem.
This hasn't affected any of my full, delta or mirror backups, on any of the NFS targets - but it does affect two different Pool metadata & xo config backups. Both on different NFS targets on different schedules.
It's an infrequent failure, sometimes not failing for a couple of days, but sometimes failing up to 3 or 4 times per day - this is on an hourly schedule.

My most recent failure on the hourly job was yesterday morning, the one before that was almost 24 hours earlier.
This is currently on Xen Orchestra, commit 24913 but it was also noticeable on a version from the end of July.
From what I've read, I'm guessing the fix will be in the main branch soon enough and an update will solve it, but if there's any useful information I can provide, please let me know.
