I have witnessed this same issue on an Intel Mac Mini, after a few
gigabytes of network transfer. The workaround I found was to disable
MSI. If I remember my testing correctly, I tested this fix in 7.1, then
reinstalled FreeNAS (6.4) to try it there.

mskc0: <Marvell Yukon 88E8053 Gigabit Ethernet> port 0x1000-0x10ff mem
0x90200000-0x90203fff irq 16 at device 0.0 on pci1
mskc0: Unexpected number of MSI messages : 0
