I am receiving the following err message on an AP121:

mDNSResponder: reorganize relay packet failed

It is immediately preceded by the following info message:

mDNSResponder: Get Answers failed when relaying

Can you help me make sense of this?

Hi Sean

The 'mDNSResponder: reorganise relay packet failed' sounds like it is trying to fragment the packet, and mdns doesn't support fragmented packets.

The mdns messages are generated if you use apples bonjour over the network, are you using the bonjour gateway feature?

Yes, we are using the Bonjour Gateway feature and are using Apple's Bonjour over the network.  We have approximately 150 Apple devices.  We also have 50 or so other devices, mainly printers running Bonjour.  We have plans to migrate to all Macs over the next few years bringing our Apple devices to about 1500.

In fact, we are trying to test this AP exclusively as a Bonjour Gateway.  We have had issues with our previous Bonjour Gateway solution provided by another vendor.  We had this Aerohive AP lying around.  After discussions with an Aerohive sales representative concerning the free Aerohive Gateway, we were told the AP could do the same thing.

What can we do about preventing the fragmenting of the packets?

I found these two warn messages occurring about two minutes after the "reorganize" messages.  Would these have anything to do with this whole issue?

2014-12-16 09:09:57 warn    mDNSResponder: Client application bug: DNSServiceResolve(holmanmmac\032(3)._rfb._tcp.local.) active for over two minut                            es. This places considerable burden on the network.

Hi Sean

What HiveOS version is this AP121 running acting as your bonjour gateway?

Have you got multicast routing enabled on your network also?

HiveOS 6.2r1.1924 and no multicast routing.
