Hi All,

I recently upgraded to 10.8.x, and my Mac Pro is now in the habit of going down every night (I come in in the morning, and can't wake it up, and have to force-restart).

Can anyone help me track down which process is causing the problem?

Cheers!

Chas

Check the Console for the last messages before the restart.

Ah, thanks for that, I'd been looking in the crash logs for a solution.

Here are the last several entries in the Console before the restart:

03/07/2013 09:49:15.487 mDNSResponder[54]: ActivateLocalProxy: No service for interface utun0
03/07/2013 09:49:16.708 configd[17]: network changed: v4(en0-:192.168.0.32) DNS- Proxy- SMB
03/07/2013 09:49:16.718 mDNSResponder[54]: DeregisterInterface: Frequent transitions for interface en0 (192.168.0.32)
03/07/2013 09:49:16.728 awacsd[70]: InnerStore GetWakeInfoForZone: zero address for 169271314.members.btmm.icloud.com.
03/07/2013 09:49:16.733 awacsd[70]: KV HTTP 0
03/07/2013 09:49:21.736 awacsd[70]: KV HTTP 0
03/07/2013 09:49:26.000 kernel[0]: HPTRRController::setPowerState(0xffffff802cfa1000, 1 -> 0) timed out after 10141 ms
03/07/2013 09:49:26.000 kernel[0]: Wake reason: RTC (Alarm)

Any idea if any of these are relevant? (a google search for "HPTRRController + OSX" didn't come up with much useful info).

Thanks again for the help,

Chas

What are the messages immediately following the wake reason?

Try going to System Preferences > Energy Saver > and uncheck the Wake for network access checkbox.

That should fix this particular issue.

Many thanks for that, unchecked! May I ask: what led you to this conclusion?

And there were no messages following the wake reason (unless you count the restart sequence, several hours later).

Cheers!

I've had the same issue a while ago, and Google triggered the memory.

You can check all the process, Disk usages and %CPU usages by Activity Monitor tool.
Go to utilities then click on Activity Monitor , it will show all your process running in system

And this is relevant to this thread, which is about a Mac that has been crashing in its sleep, how exactly?
