Tenho um cluster Proxmox com dois servidores físicos, pve e pve2. Eles são Dell R710s idênticos com 96 GB de memória e 1 TB (RAID-10). Por alguma razão que ainda não identifiquei, o pve2 irá desligar e ligar. Verifiquei os logs de HW por meio do iDRAC e não há alarmes ou erros.
Sou bastante novo no Proxmox, então não sei onde procurar logs de erros fora dos locais habituais do Linux, comoregistro de sistemaedmesg.
Aqui está um trecho do meu syslog quando a reinicialização aconteceu: (@ 30 de dezembro 16:54:01)

Alguma sugestão sobre o que pode ser ou onde posso verificar?

Pode ser uma falha de hardware, o mais comum é a RAM com defeito.
Execute um memtest no seu servidor para descobrir.
