This is a prod cache_text machine. I've depooled it explicitly from service for now.
14:11 < icinga-wm> PROBLEM - Host cp1052 is DOWN: PING CRITICAL - Packet loss = 100%
RAC console still works, can log in, host is still up. No ethernet link, with the following in dmesg:
[Sat Oct 22 14:11:16 2016] bnx2x 0000:01:00.0 eth0: NIC Link is Down
While I'm looking at dmesg, there's also notable temp threshold events in dmesg ~4 days ago, which reminds that we still have T125205 outstanding to monitor for thermal issues...
