I had issues with what sounds like a similar configuration last year.
Firstly, UseVolumeOnce is depreciated and should be replaced with
"Maximum Volume Jobs".
However, "Maximum Volume Jobs" (and hence I assume UseVolumeOnce) does
not work when running concurrent jobs. This is noted in the manual.
See "Maximum Volumes Jobs" in the Pool Resource section of the 5.2.x
manual.

WatchGuard Dimension instantly turns raw network data into actionable
security intelligence. It gives you real-time visual feedback on key
security issues and trends. Skip the complicated setup - simply import
a virtual appliance and go from zero to informed in seconds.
