mDNS_Register_internal: ERROR!! and arp {router MAC} attempts to modify permanent entry errors

[qwertymodo]

I've been getting a regular deluge of the following errors in my logs for awhile now, but with the 9.10 upgrade, I get them even more than before.

Apr 6 18:26:39 freenas mDNSResponder: mDNS_Register_internal: ERROR!! Tried to register AuthRecord 000000080147ED60 freenas.local. (Addr) that's already in the list
Apr 6 18:26:39 freenas mDNSResponder: mDNS_Register_internal: ERROR!! Tried to register AuthRecord 000000080147F180 10.0.1.10.in-addr.arpa. (PTR) that's already in the list

. . .


Apr 6 18:26:40 freenas kernel: arp: 00:ff:60:5f:83:99 attempts to modify permanent entry for 10.1.0.1 on epair0b
(identical message repeated for all epairXb devices)

10.1.0.1 is the LAN address of my router, which is the default gateway for the network. This is wreaking all kinds of havoc on my network, as every time I see these messages pop up, it also results in losing internet connection for about 5 minutes at a time. Any ideas of how to troubleshoot this issue? I've seen mention of turning off hostname lookup in CIFS, but I already have that turned off, as well as CIFS disabled entirely.
