I put my 1 year old iMac (running OSX 10.8.2 with all updates) to sleep in San Diego. I then tried to wake it up from Vegas using my other iMac (same OS) using the following command:
Cmd-K >> "vnc://192.168.1.49" #[running over a VPN]
I've done this sort of thing a million times with no problem but today the San Diego iMac didn't wake up. I sent my I.T. guy to investigate. He said the screen was black, and the machine was unresponsive to keyboard or mouse input. The harddisk was still running. The iMac was hot to the touch (as all iMacs are when they've been awake for an extended period).
He turned the machine off and turned it back on. Everything looked normal. He ran:
Cmd-Space >> "console"
The log was completely full. There were 4,000+ messages, each with the exact same date/time stamp and message. It was as follows:
2/12/13 11:29:29.000 PM kernel: (default pager): [KERNEL]: ps_allocate_cluster - send HI_WAT_ALERT
It's like the machine was trying to wake itself at 11:30pm for some reason. And it failed. Everything appears ok now but this event concerns me. Any remedial action I should take?
