I am experiencing the same. Saw some folks over at the Apple support communities also experiencing it. Looks like VMWare Fusion is involved somehow for sure.

Yes, and I have a feeling it may be memory related. I have 4Gb on my MacBook Pro, and I get the sneaky suspicion that 10.7.2 is using more memory than prior releases. I was hoping not to have to upgrade!

I am also having the same issue. Within an hour of starting a simple Windows 7 x64 VM - using 1 core and 2GB RAM - the processor usage and memory go through the ceiling on the Dock process. Literally using all available CPU processes and over 2-3GB of memory itself. This is not a usable or acceptable bug. I need to use Windows 7 for work and I cannot afford to spend time restarting things every 2 hours. It uses so many resources that time machine cannot back up and eventually the whole system becomes unusable - and not in the generlly thought of way but in th way I remember windows being when explorere and everything that goes with it was crashing. I have some theories and I am going to try to turn off the 3D aceleration and see if that makes a difference but I really hope this gets the attention of VMWare. I enjoy a lot of the feature the seperates Fusion from Parallels. I work in IT and need to be able to interchange and use different VM's on the fly before they go to our ESX server and/or other VMware workstation PC's. If it wasn't for that fact alone - I may very well already be downloading Parallels. I will update with how the 3D adjustment goes.

UPDATE (over an hour later): After Shutting down the VM and going into the settings - to help you that dont know (Virtual Machine>Settings>Display) and turned off the 3D Acceleration (which I don't need for my work applications) the problem seems to have stopped. The dock is now not going over 32 MB of memory used and the CPU use is stable (generally arond 0.1% or lower) !!!!

I hope VMWare fixes this soon, but for now this will be a decent workaround. Hope this helps more of you! I will repost this over at apple support.

Please make sure that when you do this - you shutdown windows. do not use suspend or any of the other handles - it also would help to know if you have a newer (mid 2010 or later) device - nd make sure that Auto graphics switching in ON (System Preferences(on the mac) > Energy Saver>Checkbox at the top (Automatic graphics switching).

I'll throw my name in as having the same problem.  It is a pain, consuming battery like crazy.  I have been experiencing it since 10.7.1 though.  I get the same console.log messages as well.

jcon,

A few hundred? It really should NOT be using that much; mine when this issue is resolved, only uses 32MB of RAM.

I opened a related support request, anyone else opening one should probably reference it: 11109649910, (that is if you can figure out how to open a case, what a pain that was...)
