My 12" powerbook has done the same thing. It seems like something very rarely stops it from sleeping properly.. I dunno.
But it's been a longstanding (if rare) problem. The big annoyance for me is not the heat or fans (I think it might be a little cooler than the MBP), but that when I pull it out my battery is completely drained, and it takes 5 minutes of charging for it to wake up again.
Mine does this as well. Not sure why. I find that disconnecting all the USB/video cables, waiting a bit, THEN closing the case makes this not happen.
Sounds like you need a Mac Doc.

You always have so many computer problems. You should switch to using Macs.
That's a common problem with the Pro. There might be a firmware upgrade out? Those ones are called 'SCM updates'.
A coworker had his plastic building ID next to his Pro in a backpack when this happened, totally melted it -- his picture wasn't recognizable afterward.

I don't understand why you don't just turn it off?
Maybe I'm just far too use to the fact that windows laptops next to never hibernate properly so seems simple to just turn it off and not bother with it all.

Well, you see, the problem is Mac users have this long experience of having things just work and develop high expectations from this, unhealthy as that may be.
I've had the same thing happen on my MBP. Usually, what I do is open up the Activity Monitor app right away after resuming -- 100% of the time (for me at least), it's been SSH Agent wound up in a tight loop, consuming all of the CPU. After resuming from sleep, SSH Agent usually finishes its death spiral and crashes. I hear the reason for this kind of thing happening is that the Mac shuts down all network connections when you put it to sleep. Some apps handle this well. Others go into tight loops, consuming a bunch of memory and CPU when the network disappears out from under them. Alternatively, there could be some app preventing the machine from going to sleep (http://developer.apple.com/qa/qa2004/qa1160.html
). In any case, what works is (as mentioned above), disconnect all devices first, AND shut down network apps that have "always on" network connectivity. E.g., Adium, ssh tunnels, etc.

Re: SSH Agent
Interesting ... thanks!
That happens to my 12 in powerbook if the lid pops open just enough to start the wakeup and then closes before the screen comes back on.
I've read it's a known problem. There's also "moo" sound from the fan. Lots of folks ended up sending it to Apple for a fix and waited for too long. After my last Mac, SE/30 in 1993 while at Dartmouth, I've got a MacBook recently, and it shuts down randomly, also a known problem. Try the SMC upgrade first, exchange for a new Core 2 Duo Pro second! :)

Don't you mean a "Moof" sound?
Sadly, I've been having the exact same problem. I've tried a number of things, all to no avail:
- Reset PRAM
- Install Consolidated Update
Sleep functionality doesn't appear to be broken, per se - I can explicitly choose Sleep from the Apple menu and it works fine.
Sooooo, I'm training myself to explicitly Sleep my MacBook before closing it - yes, this sux, and it's terribly non-Mac like. :-(

Cranking up the internal fans
I've started using this and it helps with the overheating (not the sleeping):http://126.96.36.199/~eidac/software/page5/page5.html
You use it to reset the _minimum_ fan speed, which Apple defaults to 1000 RPM. I've up'd my minimum fan speed to 2500 RPM. It keeps the computer cooler and minimizes overheating when it doesn't sleep. I'm a bit concerned about burning the fans out, but that's preferable to burning the freak'n computer out.
If nothing else, you can use it to monitor your computers internal heat - it's hot as hell inside these little boxes.

Re: Cranking up the internal fans
Setting the minimum fan speed won't help much when the laptop is supposed to be asleep and is locked up in a small, confined, and insulated location where the heat can build up quickly. Brad's laptop obviously woke up while in the bag, got hot under the collar, and cranked the fans up full to try coping with it.
You are not the only one, friend.
Me and my iBook are sooo not talking right now.

When did it start happening?
I'm not sure when this started happening to my Mac, but I think that's it's been doing it since the last system update. I'm wondering if the last update weakened the algorithm for detecting that the lid is closed, since sleeping works but the lid closure doesn't appear to trigger it.
hey, Brad! :)
cheers from moscow - we've got really fun (and totally unexpectable for me) party at my return from egypt :)))
overheated notebook in a sleep mode? may be it's the reason to switch for iX86 and freebsd/gnome?.. :) more than 7 years of totally stable uptime. with reboots for software upgrades, of course. ah!.. and i've changed broken power supply blocks, once for each server. mac is a fashion, i beleive :)

I run Debian or Ubuntu on almost every other machine except my laptop. The MacBook Pro is nice because I can run Windows, Mac, Linux, Solaris all on the same box, using Parallels.
I don't catch the problem. You forget to switch it off? =)
