[Nut-upsuser] Loosing comms with UPS

[Alain Williams]

In my system log file I get messages like:

	Jul 18 13:05:12 mint upsd[4025]: Host 192.168.145.12 disconnected (read failure)
	Jul 18 13:10:12 mint last message repeated 5 times
	Jul 18 13:10:12 mint last message repeated 4 times


and broadcast messages like:
	Communications with UPS mintups at mint.phcomp.co.uk lost
30 seconds later:
	Communications with UPS mintups at mint.phcomp.co.uk established

This is a Liebert UPS connected over USB.

Any idea what is happening ?


On another point:

I had the system hang again when I stopped upsd. I had moved all the config
files from /usr/local/ups/... to /etc (since my /usr is a separate mounted
file system and so not available in the last stages of powerdown).

The contents of /var/log/messages is below. I have (at other times before/since) stopped/started
upsd without probelms. No other info available. Kernel: 2.6.9-55.0.2
