I think I’ve seen that — IIRC it’s caused by the cubie’s clock being set to 
1970. If you run something like

ntpdate -s pool.ntp.org

to reset the clock and then

service xcp-rrdd restart
service xapi restart

It should come back to life. You can tell if xapi is happy using

xe host-list params=enabled

If the result is ‘false’ (or some other failure) it’s probably because some 
other service has failed. Have a look at ‘message-cli diagnostics’ — it’s a bit 
hard to read so feel free to paste the output here.

I think we need to rethink the protocol between xcp-rrdd and xapi to prevent 
this from happening.

Don’t worry! :)
