O Windows Server 2012 está gravando um arquivo .LOG de 1 megabyte no windows \ system32 \ dhcp a cada alguns segundos

Question

Eu tenho um sistema Windows Server 2012 que está executando um servidor DHCP. A tentativa de parar o serviço levou mais de uma hora para ser concluída. Ele estava escrevendo gigabytes de arquivos .LOG para C:\Windows\System32\dhcp todos os dias (atualmente tem cerca de 16 GB de tamanho).

Alguém viu tal problema e como você corrige isso?

Nenhum evento aparece no Visualizador de Log de Eventos do Windows na área do servidor DHCP, por isso não tenho certeza do que esses arquivos realmente são. Eles são arquivos binários nomeados assim:

j5000A1C.log j5000A1D.log

Cada arquivo que começa com a primeira letra j tem 1 meg de tamanho e há cerca de 16 gigabytes deles.

Também existem alguns registros legíveis por seres humanos, incluindo dois para os quais estou mostrando trechos de:

Esta parece ser uma atividade para o log DHCP-para-ip-v4 de hoje:

Estou realmente perplexo com o que são esses arquivos "j.log".

Eu tenho servidores DHCP ipv4 e ipv6 em execução, mas o servidor ipv6 não tem opções configuradas. Isso significa que o que eu vejo é que nenhuma caixa de seleção está marcada, então eu acho, 100% de opções padrão para DHCP-para-ip-v6:

ParecequeoservidorDHCPestavaemummodode"trem de fuga" e que reiniciar o serviço fez com que parasse de fazer o que foi mencionado acima. No entanto, gostaria de saber o que causa isso e se, de alguma forma, posso ver o que está gravando em todos esses arquivos de log. (Alguém nos comentários me diz que este é o arquivo de log de transações do formato MS Access, usado para o banco de dados do serviço DHCP) Atualizar O comportamento do servidor DHCP do Windows Server 2012 não reapareceu. Parece ter sido uma vez um surto.
