strange crash during sleep

Message #1 - Posted 2005/03/19 - John McLachlan

Hey all. For a new 17" imac. Been a happy camper.

This morning, did a lot of audio work. Quit most of the apps, and put the mac to sleep. all is well.

Came home. screen is dark. 'sleep light' isn't pulsing, and the CPU fan is buzzing like a chain saw. Couldn't wake up the computer at all, had to power-button restart. Scanned all the logs, and there was no log entry at all between the sleep and the hard restart. Sample log segment below.

thoughts?

Mar 19 10:12:56 localhost kernel: AirPort: New Group Key, Idx 2 Mar 19 10:57:22 localhost mDNSResponder[218]: mDNSResponder Sleeping at 162630318
Mar 19 10:57:22 localhost SymMissedTask - parent[263]: sleep demand recorded: Sat Mar 19 10:57:22 2005
Mar 19 18:06:36 localhost syslogd: restart
Mar 19 18:06:36 localhost syslogd: kernel boot file is /mach_kernel

That's the sleep panic that seems to be common in recent Macs. Look for a /Library/Logs/panic.log file.

Well, I'll believe 'sleep panic' but no panic.log on the HD...

If you are running OS 10.3.8, there are *pages* of discussion of this problem in a macfixit.com report. However, you can access the macfixit.com reports only if you are a member (very worthwhile, in my opinion).

You might want to search the macfixit.com forums on this topic.
