h1lsc0 has crashed, looks like kernel panic on general core, model cores continue to run, no DAQ issues

h1lsc0 general core looks like it has crashed. The models continue to run. No IPC problems on receiving models, no DAQ problems outside of h1lsc0.

Gabrielle is on site and is taking a picture of h1lsc0's console before we start the recovery process.

Console was unresponsive. I remotely disabled h1lsc0's Dolphin switch port and Gabrielle pressed the RESET button on the front panel.

Trending the CPU usage of H1LSC0 and one of the EPICS channels, it looks like the crash happened around Oct 06 2018 12:56:58 UTC. This should be 6am local time
