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

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

I have the same issue. My mac is 10.6.8 and I'm using XCode 4.2.

Just try:

Go to the Macintosh HD > Developer > Platforms > iPhoneSimulator.platform > Developer > SDKs > iPhoneSimulator5.0.sdk > System > Library > LaunchDaemons directory and then open the plist file from there. Locate the "Disabled" key and change its value from "NO" to "YES".You need to change permission in the file and also its parent folder in order to save the new permission of plist file before modifying in XCode.

Hope this help.

Frankie, this is exactly what I ended up needing to do on Friday after another laptop's fan started whirring like crazy.

My recommendatiopn of renaming the bin is BAD since the console will output many many messages of attempting to lainch the BTServer.

Yeah, I'm gonna recommend against my solution since it spits out a lot of console window information.

It will work in a simple case, but Frankie's recommendation is the best and has complete instructions.

@elguanodev: There IS a way to spot the high CPU usage before the fans start revving: I use MenuMeters. This shows the CPU load in the menubar as a small graph. Launching the simulator usually also raises CPU usage a lot. (2Ghz i7 MacBook Pro) After quitting the simulator, the graphs usually return to normal, but not always. (That's why I am here in this thread, responding to your post :-)
