Sleep Issue With MacBook Pro Continues After Lion 10.7.3 Combo Update

This issue came up in the Lion rant thread, but since it is off topic there, I started this thread to see if others are having the same issue. It started with this observation from CubaMark:

It will continue to go through this cycle... shutting off the HD and then springing back to life. After a few occasions of finding the laptop closed and unexpectedly warm, I clued in.

A restart clears it up - so some process that is being launched (either native to Lion or otherwise) is preventing sleep...
This morning when I went to open my MBP it was hot. I watched the sleep indicator light and it was on full bright for about 30 seconds, then it would fade for about five seconds and glow brightly again for 30 seconds. The Apple logo in the top case was glowing brightly. The machine was definitely not sleeping.

When I opened the screen, there was an Apple message that another device was using my IP address. I assume that it referred to the fact that I was using my iPad, reading an eBook in bed. I get this message a lot when I use the iPad. Is there any way to alter something to avoid the message?

All this after updating to 10.7.3. using the combo updater. So much for Apple's supposed 'sleep' fix in that release.

Anyone else experiencing this behaviour with a MBP or a MB?

For now my MBP is shut down after use as I don't think this is good for the MBP, 'cooking' all night.

Run TM backup and erase and install. See if the issue persists on a clean install. If it does then it's a lion or hardware problem. If it doesn't it's more likely something 3rd party software related

it does sounds like your router is immediately giving the ip address to your ipad once your MPB is in sleep.

i would suggest verifying the DHCP server to reserve ip addresses for at least 24hours before it would assign the same IP again.

default on most routers is 7 days.
