[11:17] <icinga-wm> PROBLEM - Host cp3057 is DOWN: PING CRITICAL - Packet loss = 100%
I thought about T238305 first, but after connecting through serial port, the host seems up and responsive, so probably network?

Edit: it looks that it had soft-crashed for a while, but later fully as seen on logs, so most likely T238305 :-(
