O controle dos pais inunda o system.log com erros

Eu estava cavando ao redor para se divertir, e eu achei que o system.logfoi INUNDADA com erros. Aqui está um exemplo.

Qual seria o tamanho de um system.logarquivo médio e seria "limpo" periodicamente por processos mensais ou algo assim? Aqui está o meu ls -l | grep system.log.

Eu tenho meu computador há apenas 2 anos. Se houver algum problema, agradeceria seus pensamentos e ajuda.

Veja se você encontra o arquivo de log de atividades do Controle dos Pais. Verifique se ele não está em um volume completo, verifique se ele não está corrompido (tente afastá-lo ou excluí-lo e permitir que o sistema o recrie) e verifique se ele possui as permissões corretas (talvez execute uma "Reparar permissões" nesse volume em Utilitário de Disco)

Veja a resposta a seguir para obter mais informações sobre esses arquivos. Como posso visualizar os arquivos de controle dos pais do Mac OS X com o formato .data?

Quanto mais eu leio essa outra pergunta e resposta, mais convencido estou de que um ou mais dos seus arquivos de log dos controles dos pais (que na verdade são arquivos CoreData .data, não logs de texto sem formatação) estão corrompidos.
