BTServer causing high CPU utilization

Just got a new MacBook Pro with OS X Lion and updated to 10.7.1. I've seen the BTServer process cause high CPU utilization twice now. One morning I also noticed that the fan was running loudly while the lid was closed and the computer was locked up; I had to force power it off. Anyone seeing similar issues? Doing a search for BTServer on Google or even here in the Apple Support Communities does not bring up anything related to Lion at all, only iPhone-related articles.

MacBook Pro, Mac OS X (10.7), 2.3GHz Intel Core i7, 8GB 1.3GHz

okay, follow up here - looks like BTServer is launched when I have the ipad simulator running when doing xcode work. quitting the simulator will also end the process.

might be a necessary service for the ipad simulator, but whoa.. lets take it easy on the cpu, mmkay? 🙂

Same problem as everyone else - running Xcode 4.2 Master. I just submitted a bug report to Apple and referenced this discussion.

BTServer stands for Bluetooth server. I don't think we need Bluetooth in simulator !

You can safely disable it.

Same for me. On Snow Leopard and XCode 4.2. It seems that it stared also with the iOS Simulator.

Just rename the BTServer, the simuator will launch faster too.
