Sudden unexplained shutdowns - unrelated to Sleep

Over the past couple of days I've suddenly had occurences of spontaneous shutdown. Sometimes related to sleep issues (though user induced sleep rather than on the energy-saving timer), but usually it just happens spontaneously. I cannot for the life of me work out why this has suddenly started happening - the only thing I can pinpoint is that prior to installing the most recent Security Update is never happened, and since then it has happened several times a day.

My imac is not one of the ones covered under the repair extension programmes for power and video issues. And I've already tried resetting the PMU.

It's difficult to point to anything specific that might be causing it, but below is the system.log from the most recent incidence. As you can, things suddenly seem to get intensely busy... Any thoughts or speculation as to what is causing this.

Sometimes a Mac running hot will cause this.

Here's the free Temperature Monitor to check it.

Also, Repair Permissions before and after every update.
This is for sleep, but one of them may be your issue;
A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:

-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--
(username is your name or System Administrators name)

-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.

Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.11 Combo update (PPC not for Intel Macs). Others reading, download the combo update that applies to you!
