Nice suggestions ;-) I see some [watchdog/N] and one [watchdogd] kernel threads, along with a "kernel: [ 0.116002] NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter." line in the kernel log, but no user-land watchdog daemon: I'm not sure if the watchdog is actually active. There ARE chassis/BMC/IPMI level events, one of which is "CPU CATERR Fault", with a timestamp matching the timestamps below, and no more information. If I understand correctly, this is a signal emitted by the CPU, to the BMC, upon "catastrophic error" (more than "fatal"), which the BMC must respond to the way it wants, Intel suggestions including resetting the chassis. https://www.intel.in/content/dam/www/public/us/en/documents/white-paper s/platform-level-error-strategies-paper.pdf Does that mean that the hardware is failing, or a neutrino just crossed some CPU register? CPU is a Xeon D-1521 with ECC memory. > Kind regards, Many thanks! > > Caspar > > 2018-07-21 10:31 GMT+02:00 Nicolas Huillard <nhuill...@dolomede.fr>: > > > Hi all, > > > > One of my server silently shutdown last night, with no explanation > > whatsoever in any logs.
