Hi, The last friday in the early morning a node reboot alone, but i don't know what trigger that, I chek the logs and see the next lines:

Memory failure: 0xca06f60: Sending SIGBUS to CPU 1/KVM:4190709 due to hardware memory corruption
QEMU[4190647]: kvm: Guest MCE Memory Error at QEMU addr 0x7aacf4360000 and GUEST addr 0x1dc560000 of type BUS_MCEERR_AR injected
VM 316 qmp command failed - VM 316 qmp command 'query-proxmox-support' failed - unable to connect to VM 316 qmp socket - timeout after 51 retries

Is the use of the memory or a damage ram or why happened, if someone have the same problem help me a lot or how i can resolve it, that line are before the reboot

Hi, @ferp
Start searching the reason by using Memtest program (reboot the host and from the boot menu select Memtest).
Then leave it running for a few "passes" (depending on the amount of RAM - a few hours or a night).
