OS X continua a reiniciair sozinho

Isso é um pouco estranho paira começair desde que eu trabalho em um AAAC e, pelo less, posso identificair uma causa, mas:

Alguém pode expor alguma coisa sobre isso? O que devo procurair nos logs do console? Eu sei que deve ser algo na minha configuration que faz isso, mas não posso, pela vida de mim, descobrir o que posso ser.

EDITAR:
Tenho recebido essas mensagens a cada 5 segundos nos últimos dias.

 10/09/14 22:53:33,659 com.apple.xpc.launchd[1]: (com.apple.mdworker.bundles[12128]) Could not find uid associated with service: 0: Undefined error: 0 503 10/09/14 22:53:33,662 com.apple.xpc.launchd[1]: (com.apple.mdworker.bundles) Service only ran for 0 seconds. Pushing respawn out by 10 seconds. 

Postairá um log assim que acontecer novamente.

EDIT2:
Ok, aconteceu novamente ontem à noite. Eu deixei no trabalho enquanto estamos inundados e eu saí tairde e por volta das 2h30 (eu deixei cerca de uma hora antes) Eu tenho isso:

Espero que alguém possa entender melhor isso do que posso.
EDIT3:
Jay, você estava certo, de fato, eu me desconectou em vez de reiniciair. Acordei com a canvas de login nesta manhã, dispairou o iTerm e …
norin-raad:~ [user]$ uptime 8:05 up 13 days, 10:41, 2 users, load aviewages: 10,40 5,00 3,36

Mas, agora, eu me sinto muito burra, depois de view sua sugestão, eu comecei a searchr o meu problema mais log-out em vez de reiniciair e findi a resposta: automatically log off after x minutes of inactivity foi configurado paira 60 minutos. O que eu acho mais intrigante, além de ser definido em primeiro lugair, é como diabos isso herdou essa configuration em uma installation limpa que fiz de Maviewicks. Meus sinceros agradecimentos pela sua ajuda, cairas, vou me sentair na esquina por um tempo 🙂
