[avahi] avahi-daemon stuck registering.

[Scott Garman]

Hello,

I have some identically configured embedded systems running avahi for
service discovery which are on different networks. On one system, avahi
is running just fine. On the other, avahi is getting stuck while
registering. Restarting the avahi daemon, dbus, or the OS is not fixing
the problem.

What can I do to help troubleshoot this issue further?

Thanks,

Scott
