Unable to create ZVOL error since upgrading to 9.3-RELEASE

I have a nightly backup job that creates a snapshot of my ZFS pool,
mounts the snapshot file sets appropriately under /backup, and then
rsyncs that hierarchy to another system. This worked fine under
9.2-RELEASE and before.
Since upgrading to 9.3-RELEASE, I get the following error in the daily
security run output for that machine:
redmine kernel log messages:
+++ /tmp/security.6itlEbCD 2014-07-30 03:01:10.401183488 -0400
+ZFS WARNING: Unable to create ZVOL sys/SWAP/swap at backup (error=17).
I have swap on a ZFS ZVOL: sys/SWAP/swap. I create the snapshot via
"zfs snapshot -r sys at backup" ("sys" is the name of my ZFS pool).
Does anyone know why I should be getting this error now? The same
script running on the same machine gave no problems under 9.2-RELEASE.
I started getting this message as soon as I upgraded to 9.3-RELEASE.
Did some sysctl default change between 9.2-RELEASE and 9.3-RELEASE that
changed the behaviour of ZVOLs and snapshots?
The message isn't fatal, but it is annoying to have it appear every day
in the security run output.
