If this is a recent sever (ivybridge/haswell/broadwell) then I’ve seen the “edac” kernel module prevent SEL from showing faults when a MCE/machine-check-exception occurs. Disable edac and poof server stops crashing and/or SEL shows something useful(ECC/MCE). Did you check /var/log/mcelog? _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
