Stop using Onyx.
But more importantly find out if the RAM has gone bad, or your disk is too full*:

i'm noticing this identical behaviour on my 27 inch core i7 imac. I've used the built-in diagnostic tools and it reported that all is well. I've checked my disks using Disk Utility and all is well.
I've even had the lock up occur while booted from the install DVD, so that tells me that it isn't anything related to my OS installation or setup.
And like you, it seems to only happen during idle moments. It hasn't yet happened while I'm actively doing something on the machine. That could be a coincidence though, i'm not sure.
I just phoned Apple support and they said I have to take it to a tech centre for further diagnostics. Hopefully they are able to get to the bottom of this problem.27 inch core i7 imac, Mac OS X (10.6.3)
Frank, the locking up only has occurred when I haven't been using it. However, yesterday it locked up while I was running a RAM test, to see if any of the modules were bad (they ended up being fine).iMac 2.66 i5 Quad with 8 GB RAM, Mac OS X (10.6.3), Nikon shooter
it seems we're not alone with this sort of issue. There are similar postings at the following thread:
so far my lock ups have only occurred when the computer is idle, never when I'm working on it. So if I leave the computer and it only has one or two things running (eg say a web browser and chat window) then most likely when I come back it will be frozen.
If, however, I run many apps, like apache, and mysql, and rails, and leave those running, then it makes it through the night and is still running just fine when I come back in the morning.
I was hoping that it might be related to the energy saver setting 'Put the hard disk(s) to sleep when possible', but I turned that off earlier tonight and I experience a lockup since then.
I have two USB 2.0 external disks and a USB 2.0 flash drive plugged in. I will try unplugging those and see if the computer still locks up.
Oh, and yesterday, I did get a lockup after having run Disk Utility by booting off of the install disk. Disk Utility reported all was well...then i just left the computer for a few minutes and came back and it was locked. So that tells me that my problems isn't a software conflict or anything like that on my install of Snow Leopard. But it could be a firmware issue or an issue with Snow Leopard.
Anyone have any theories?
I spoke to Apple yesterday and the only thing they were able to suggest was to take it for service. I'm not convinced that its an isolated issue with my computer though.27 inch core i7 imac, Mac OS X (10.6.3)
Same thing happening to my one-week-old 27" i5. In my case it freezes and I get a little round multicolored ball as a mouse pointer and the only way to go is to push the button and turn it off.
It happened 4 times so far this evening. I also have two external hard disks, but I cannot afford not to have them, all my photos are there!
My computer freezes when I run lightroom and photoshop, or lightroom and safari at the same time.Imac, iMac 11,1 Core i5, 2.66GHz
Stop turning off your machine that way! I believe what is occurring is you are simply running out of memory. Run Activity monitor and see where you memory is being used. Photoshop, Lightroom and Safari all use a lot of memory and if you use them all at the same time you will get to a point where your machine run's out of available RAM and has to do memory swapping. Memory swapping is very slow and would explain your spinning beach ball. I suspect if you upgrade the RAM in your machine that will take care of your problem.
You are doing more damage than good by force shutting it down so please stop it before your damage your OS.

Frank and Sergio,
Please start a new topic thread here:
You'll get a wider audience and won't confuse Ghozer with solutions that don't apply to them. Similar issues, don't necessarily mean similar cause. Especially if the solutions offered here fix Gozer's problem, and they don't fix yours.An Apple user since 1981, Mac OS X (10.6)
Thanks. Yes, let's not confuse to situations. The beach ball is not the issue I'm reporting. It certainly isn't a lack of memory either (8 GB of Apple brand RAM) and the problem has happened shortly after a reboot (but usually it happens after a long period of inactivity (as opposed to a short period).
I've also unplugged my external USB 2.0 drive to see if that would solve the problem. It did not. I still have a couple other peripherals plugged in. Maybe I'll try taking those out but the problem isn't consistent in how long it takes to happen. I might be waiting a week. Or, it might happen tonight. I just need to call Apple Support I think...but I just know they are going to tell me to take it in....iMac 2.66 i5 Quad with 8 GB RAM, Mac OS X (10.6.2), Nikon shooter
