Falhas freqüentes de alocação de páginas em um KVM

2

Ultimamente o meu servidor tem estado a descer com bastante frequência. Acontece quase todos os dias de manhã cedo.

Olhando para o syslog, encontrei muitos deles:

Oct 11 06:51:12 pleskvm kernel: [1895007.359087] vballoon: page allocation failure: order:0, mode:0x310da

Os arquivos de log no nó do host proxmox estão limpos. A própria máquina usa um pouco dos recursos, por causa de uma plataforma de hospedagem na web, mas ela sempre foi executada até recentemente, quando essas falhas começaram a ocorrer. Você poderia me apontar a direção certa para lidar com isso? Log estendido:
