All 3 of these servers are nova-compute nodes in an OpenStack cluster, with a reasonable amount of load on them. The symptoms are the load shoots up into the hundreds, and ps stops returning. I've attached lspci -vnvn and 3 sets of syslog message traces that we grabbed on each of the 3 times it has crashed. $ cat /proc/version_signature Ubuntu 3.16.0-49.65~14.04.1-generic 3.16.7-ckt15 Please let us know if you need any further information.
