Random Network Failure


#1

Folks,

After months last year without any network drops on my Pi Zero using Jessie, of late I’ve been getting quite a few. After investigating a few potential problems I decided to install a new image and used Stretch Lite. Then installed PiAware and Dump1090

Was confident the problem was resolved but again last night network dropped.

Checked the syslog for potential issues and saw the following;

Now it also refers to PiAware Kernel responsible so am curious, what is avahi-daemon used for?

I think the avahi is the Linux implementation of Apple’s bonjour protocol. …not really used by PiAware but might be useful to connect to your Pi from within your house.

Thanks,

Eliminated that now as a problem.
